PrettyTables.AnsiTextCellMethod
AnsiTextCell(string::AbstractString)

Create an AnsiTextCell using string.

AnsiTextCell(renderfn[; context])

Create an AnsiTextCell using a render function.

renderfn is a function with the following signature:

renderfn(io)::String

that renders a string that can contain ANSI sequences into io.

context is a tuple of context arguments passed to an IOContext that renderfn receives. See IOContext for details on what arguments are available.

Useful for supporting packages that have rich terminal outputs.

Examples

Below are examples for wrappers around AnsiTextCell to print rich data into tables that make use of packages with rich terminal output.

Crayons.jl

PrettyTables.include_pt_in_fileMethod
include_pt_in_file(filename::AbstractString, mark::AbstractString, args...; kwargs...) -> Nothing

Include a table in the file filename using the mark.

This function will print a table using the arguments args and keywords kwargs in the function pretty_table (the IO must not be passed to args here). Then, it will search inside the file filename for the following section:

<PrettyTables mark>
...
</PrettyTables>

and will replace everything between the marks with the printed table. If the closing tag is in a separate line, all characters before it will be kept. This is important to add comment tags.

If the user wants to also remove the opening and ending tags, pass the keyword remove_tags = true.

The keyword tag_append can be used to pass a string that can be used to add a text after the opening tag. This is important for HTML where the comments have opening and closing tags. Thus, if tag_append = " -->", the following can be used to add a table into HTML files:

<!-- <PrettyTables mark> -->

  • autowrap::Bool: If true, the user wants to wrap the text in the cell. In this case, the option column_width contains the column width so that the text can be wrapped into multiple lines.
  • cell_first_line_only::Bool: If true, the user only wants the first line.
  • column_width::Integer: The column width.
  • compact_printing::Bool: If true, the user wants compact printing (see :compact options of IOContext).
  • limit_printing::Bool: If true, the user wants the cells to be converted using the option :limit => true in IOContext.
  • linebreaks::Bool: If true, the user wants line breaks inside the cells.
  • renderer::Union{Val{:print}, Val{:show}}: The render that the user wants to convert the cells to strings.
source
PrettyTables.pretty_tableMethod

When printing, it will be verified if table complies with Tables.jl API. If it is compliant, this interface will be used to print the table. If it is not compliant, only the following types are supported:

  1. AbstractVector: any vector can be printed.
  2. AbstractMatrix: any matrix can be printed.
  3. Dict: any Dict can be printed. In this case, the special keyword sortkeys can be used to select whether or not the user wants to print the dictionary with the keys sorted. If it is false, the elements will be printed on the same order returned by the functions keys and values. Notice that this assumes that the keys are sortable, if they are not, an error will be thrown.

Keywords

  • alignment::Union{Symbol, Vector{Symbol}}: Select the alignment of the columns (see the section Alignment).
  • backend::Union{Symbol, T_BACKENDS}: Select which back end will be used to print the table (see the section Back End). Notice that the additional configuration in kwargs... depends on the selected back end.
  • cell_alignment::Union{Nothing, Dict{Tuple{Int, Int}, Symbol}, Function, Tuple}: A tuple of functions with the signature f(data, i, j) that overrides the alignment of the cell (i, j) to the value returned by f. It can also be a single function, when it is assumed that only one alignment function is required, or nothing, when no cell alignment modification will be performed. If the function f does not return a valid alignment symbol as shown in section Alignment, it will be discarded. For convenience, it can also be a dictionary of type (i, j) => a that overrides the alignment of the cell (i, j) to a. a must be a symbol like specified in the section Alignment. (Default = nothing)
Note

If more than one alignment function is passed to cell_alignment, the functions will be evaluated in the same order of the tuple. The first one that returns a valid alignment symbol for each cell is applied, and the rest is discarded.

  • cell_first_line_only::Bool: If true, only the first line of each cell will be printed. (Default = false)
  • compact_printing::Bool: Select if the option :compact will be used when printing the data. (Default = true)
  • formatters::Union{Nothing, Function, Tuple}: See the section Formatters.
  • header::Union{Symbol, Vector{Symbol}}: The header must be a tuple of vectors. Each one must have the number of elements equal to the number of columns in the table. The first vector is considered the header and the others are the subheaders. If it is nothing, a default value based on the type will be used. If a single vector is passed, it will be considered the header. (Default = nothing)
  • header_alignment::Union{Symbol, Vector{Symbol}}: Select the alignment of the header columns (see the section Alignment). If the symbol that specifies the alignment is :s for a specific column, the same alignment in the keyword alignment for that column will be used. (Default = :s)
  • header_cell_alignment::Union{Nothing, Dict{Tuple{Int, Int}, Symbol}, Function, Tuple}: This keyword has the same structure of cell_alignment but in this case it operates in the header. Thus, (i, j) will be a cell in the header matrix that contains the header and sub-headers. This means that the data field in the functions will be the same value passed in the keyword header. (Default = nothing)
Note

If more than one alignment function is passed to header_cell_alignment, the functions will be evaluated in the same order of the tuple. The first one that returns a valid alignment symbol for each cell is applied, and the rest is discarded.

  • limit_printing::Bool: If true, the cells will be converted using the property :limit => true of IOContext. (Default = true)
  • max_num_of_columns::Int: The maximum number of table columns that will be rendered. If it is lower than 0, all columns will be rendered. (Default = -1)
  • max_num_of_rows::Int: The maximum number of table rows that will be rendered. If it is lower than 0, all rows will be rendered. (Default = -1)
  • renderer::Symbol: A symbol that indicates which function should be used to convert an object to a string. It can be :print to use the function print or :show to use the function show. Notice that this selection is applicable only to the table data. Headers, sub-headers, and row name column are always rendered with print. (Default = :print)
  • row_labels::Union{Nothing, AbstractVector}: A vector containing the row labels that will be appended to the left of the table. If it is nothing, the column with the row labels will not be shown. Notice that the size of this vector must match the number of rows in the table. (Default = nothing)
  • row_label_alignment::Symbol: Alignment of the column with the row labels (see the section Alignment).
  • row_label_column_title::AbstractString: Title of the column with the row labels. (Default = "")
  • row_number_column_title::AbstractString: Title of the column with the row numbers. (Default = "Row")
  • show_header::Bool: If true, the header will be printed. Notice that all keywords and parameters related to the header and sub-headers will be ignored. (Default = false)
  • show_row_number::Bool: If true, a new column will be printed showing the row number. (Default = false)
  • show_subheader::Bool: If true, the sub-header will be printed, i.e. the header will contain only one line. Notice that this option has no effect if show_header = false. (Default = false)
  • title::AbstractString: The title of the table. If it is empty, no title will be printed. (Default = "")
  • title_alignment::Symbol: Alignment of the title, which must be a symbol as explained in the section Alignment. This argument is ignored in the LaTeX back end. (Default = :l)
Note

Notice that all back ends have the keyword tf to specify the table printing format. Thus, if the keyword backend is not present or if it is nothing, the back end will be automatically inferred from the type of the keyword tf. In this case, if tf is also not present, it just fall-back to the text back end unless HTML is passed as the first argument. In this case, the default back end is set to HTML.

If String is used, the keyword color selects whether or not the table will be converted to string with or without colors. The default value is false. Notice that this option only has effect in text back end.

Alignment

The keyword alignment can be a Symbol or a vector of Symbol.

If it is a symbol, we have the following behavior:

  • :l or :L: the text of all columns will be left-aligned;
  • :c or :C: the text of all columns will be center-aligned;
  • :r or :R: the text of all columns will be right-aligned;
  • Otherwise it defaults to :r.

If it is a vector, it must have the same number of symbols as the number of columns in data. The i-th symbol in the vector specify the alignment of the -i*-th column using the same symbols as described previously.

Note

In HTML back end, the user can select :n ou :N to print the cell without any alignment annotation.


Text Back End

This back end produces text tables. This back end can be used by selecting backend = :text.

Keywords

  • alignment_anchor_fallback::Symbol: This keyword controls the line alignment when using the regex alignment anchors if a match is not found. If it is :l, the left of the line will be aligned with the anchor. If it is :c, the line center will be aligned with the anchor. Otherwise, the end of the line will be aligned with the anchor. (Default = :l)
  • alignment_anchor_fallback_override::Dict{Int, Symbol}: A Dict{Int, Symbol} to override the behavior of fallback_alignment_anchor for a specific column. Example: Dict(3 => :c) changes the fallback alignment anchor behavior for :c only for the column 3.
  • alignment_anchor_regex::Dict{Int, AbstractVector{Regex}}: A dictionary Dict{Int, AbstractVector{Regex}} with a set of regexes that is used to align the values in the columns (keys). The characters at the first regex match (or anchor) of each line in every cell of the column will be aligned. The regex match is searched in the same order as the regexes appear on the vector. The regex matching is applied after the cell conversion to string, which includes the formatters. If no match is found for a specific line, the alignment of this line depends on the options alignment_anchor_fallback and alignment_anchor_fallback_override. If the key 0 is present, the related regexes will be used to align all the columns. In this case, all the other keys will be neglected. Example: Dict(2 => [r"\."]) aligns the decimal point of the cells in the second column. (Default = Dict{Int, Vector{Regex}}())
  • autowrap::Bool: If true, the text will be wrapped on spaces to fit the column. Notice that this function requires linebreaks = true and the column must have a fixed size (see columns_width).
  • body_hlines::Vector{Int}: A vector of Int indicating row numbers in which an additional horizontal line should be drawn after the row. Notice that numbers lower than 0 and equal or higher than the number of printed rows will be neglected. This vector will be appended to the one in hlines, but the indices here are related to the printed rows of the body. Thus, if 1 is added to body_hlines, a horizontal line will be drawn after the first data row. (Default = Int[])
  • body_hlines_format::Union{Nothing, NTuple{4, Char}}: A tuple of 4 characters specifying the format of the horizontal lines that will be drawn by body_hlines. The characters must be the left intersection, the middle intersection, the right intersection, and the row. If it is nothing, it will use the same format specified in tf. (Default = nothing)
  • columns_width::Union{Int, AbstractVector{Int}}: A set of integers specifying the width of each column. If the width is equal or lower than 0, it will be automatically computed to fit the large cell in the column. If it is a single integer, this number will be used as the size of all columns. (Default = 0)
  • crop::Symbol: Select the printing behavior when the data is bigger than the available display size (see display_size). It can be :both to crop on vertical and horizontal direction, :horizontal to crop only on horizontal direction, :vertical to crop only on vertical direction, or :none to do not crop the data at all. If the io has :limit => true, crop is set to :both by default. Otherwise, it is set to :none by default.
  • crop_subheader::Bool: If true, the sub-header size will not be taken into account when computing the column size. Hence, the print algorithm can crop it to save space. This has no effect if the user selects a fixed column width. (Default = false)
  • continuation_row_alignment::Symbol: A symbol that defines the alignment of the cells in the continuation row. This row is printed if the table is vertically cropped. (Default = :c)
  • display_size::Tuple{Int, Int}: A tuple of two integers that defines the display size (num. of rows, num. of columns) that is available to print the table. It is used to crop the data depending on the value of the keyword crop. Notice that if a dimension is not positive, it will be treated as unlimited. (Default = displaysize(io))
  • ellipsis_line_skip::Integer: An integer defining how many lines will be skipped from showing the ellipsis that indicates the text was cropped. (Default = 0)
  • equal_columns_width::Bool: If true, all the columns will have the same width. (Default = false)
  • highlighters::Union{Highlighter, Tuple}: An instance of Highlighter or a tuple with a list of text highlighters (see the section Text highlighters).
  • hlines::Union{Nothing, Symbol, AbstractVector}: This variable controls where the horizontal lines will be drawn. It can be nothing, :all, :none or a vector of integers. (Default = nothing)
    • If it is nothing, which is the default, the configuration will be obtained from the table format in the variable tf (see TextFormat).
    • If it is :all, all horizontal lines will be drawn.
    • If it is :none, no horizontal line will be drawn.
    • If it is a vector of integers, the horizontal lines will be drawn only after the rows in the vector. Notice that the top line will be drawn if 0 is in hlines, and the header and subheaders are considered as only 1 row. Furthermore, it is important to mention that the row number in this variable is related to the printed rows. Thus, it is affected by the option to suppress the header show_header. Finally, for convenience, the top and bottom lines can be drawn by adding the symbols :begin and :end to this vector, respectively, and the line after the header can be drawn by adding the symbol :header.
Info

The values of body_hlines will be appended to this vector. Thus, horizontal lines can be drawn even if hlines is :none.

  • linebreaks::Bool: If true, \n will break the line inside the cells. (Default = false)
  • maximum_columns_width::Union{Int, AbstractVector{Int}}: A set of integers specifying the maximum width of each column. If the width is equal or lower than 0, it will be ignored. If it is a single integer, this number will be used as the maximum width of all columns. Notice that the parameter columns_width has precedence over this one. (Default = 0)
  • minimum_columns_width::Union{Int, AbstractVector{Int}}: A set of integers specifying the minimum width of each column. If the width is equal or lower than 0, it will be ignored. If it is a single integer, this number will be used as the minimum width of all columns. Notice that the parameter columns_width has precedence over this one. (Default = 0)
  • newline_at_end::Bool: If false, the table will not end with a newline character. (Default = true)
  • overwrite::Bool: If true, the same number of lines in the printed table will be deleted from the output io. This can be used to update the table in the display continuously. (Default = false)
  • reserved_display_lines::Int: Number of lines to be left at the beginning of the printing when vertically cropping the output. Notice that the lines required to show the title are automatically computed. (Default = 0)
  • row_number_alignment::Symbol: Select the alignment of the row number column (see the section Alignment). (Default = :r)
  • show_omitted_cell_summary::Bool: If true, a summary will be printed after the table with the number of columns and rows that were omitted. (Default = true)
  • tf::TextFormat: Table format used to print the table (see TextFormat). (Default = tf_unicode)
  • title_autowrap::Bool: If true, the title text will be wrapped considering the title size. Otherwise, lines larger than the title size will be cropped. (Default = false)
  • title_same_width_as_table::Bool: If true, the title width will match that of the table. Otherwise, the title size will be equal to the display width. (Default = false)
  • vcrop_mode::Symbol: This variable defines the vertical crop behavior. If it is :bottom, the data, if required, will be cropped in the bottom. On the other hand, if it is :middle, the data will be cropped in the middle if necessary. (Default = :bottom)
  • vlines::Union{Nothing, Symbol, AbstractVector}: This variable controls where the vertical lines will be drawn. It can be nothing, :all, :none or a vector of integers. (Default = nothing)
    • If it is nothing, which is the default, the configuration will be obtained from the table format in the variable tf (see TextFormat).
    • If it is :all, all vertical lines will be drawn.
    • If it is :none, no vertical line will be drawn.
    • If it is a vector of integers, the vertical lines will be drawn only after the columns in the vector. Notice that the left line will be drawn if 0 is in vlines. Furthermore, it is important to mention that the column number in this variable is related to the printed column. Thus, it is affected by the options row_labels and show_row_number. Finally, for convenience, the left and right vertical lines can be drawn by adding the symbols :begin and :end to this vector, respectively.

The following keywords related to crayons are available to customize the output decoration:

  • border_crayon::Crayon: Crayon to print the border.
  • header_crayon::Union{Crayon, Vector{Crayon}}: Crayon to print the header.
  • omitted_cell_summary_crayon::Crayon: Crayon used to print the omitted cell summary.
  • row_label_crayon::Crayon: Crayon to print the row labels.
  • row_label_header_crayon::Crayon: Crayon to print the header of the column with the row labels.
  • row_number_header_crayon::Crayon: Crayon for the header of the column with the row numbers.
  • subheader_crayon::Union{Crayon, Vector{Crayon}}: Crayon to print sub-headers.
  • text_crayon::Crayon: Crayon to print default text.
  • title_crayon::Crayon: Crayon to print the title.

The keywords header_crayon and subheader_crayon can be a Crayon or a Vector{Crayon}. In the first case, the Crayon will be applied to all the elements. In the second, each element can have its own crayon, but the length of the vector must be equal to the number of columns in the data.

Crayons

A Crayon is an object that handles a style for text printed on terminals. It is defined in the package Crayons.jl. There are many options available to customize the style, such as foreground color, background color, bold text, etc.

A Crayon can be created in two different ways:

julia> Crayon(foreground = :blue, background = :black, bold = :true)

julia> crayon"blue bg:black bold"

For more information, see the package documentation.

Text highlighters

A set of highlighters can be passed as a Tuple to the highlighters keyword. Each highlighter is an instance of the structure Highlighter that contains three fields:

  • f::Function: Function with the signature f(data, i, j) in which should return true if the element (i, j) in data must be highlighter, or false otherwise.
  • fd::Function: Function with the signature f(h,data,i,j) in which h is the highlighter. This function must return the Crayon to be applied to the cell that must be highlighted.
  • crayon::Crayon: The Crayon to be applied to the highlighted cell if the default fd is used.

The function f has the following signature:

f(data, i, j)

in which data is a reference to the data that is being printed, and i and j are the element coordinates that are being tested. If this function returns true, the cell (i, j) will be highlighted.

If the function f returns true, the function fd(h, data, i, j) will be called and must return a Crayon that will be applied to the cell.

A highlighter can be constructed using three helpers:

Highlighter(f::Function; kwargs...)

where it will construct a Crayon using the keywords in kwargs and apply it to the highlighted cell,

Highlighter(f::Function, crayon::Crayon)

where it will apply the crayon to the highlighted cell, and

Highlighter(f::Function, fd::Function)

where it will apply the Crayon returned by the function fd to the highlighted cell.

Info

If only a single highlighter is wanted, it can be passed directly to the keyword highlighter without being inside a Tuple.

Note

If multiple highlighters are valid for the element (i, j), the applied style will be equal to the first match considering the order in the tuple highlighters.

Note

If the highlighters are used together with Formatters, the change in the format will not affect the parameter data passed to the highlighter function f. It will always receive the original, unformatted value.


HTML Back End

This back end produces HTML tables. This back end can be used by selecting backend = Val(:html).

Keywords

  • allow_html_in_cells::Bool: By default, special characters like <, >, ", etc. are replaced in HTML back end to generate valid code. However, this algorithm blocks the usage of HTML code inside of the cells. If this keyword is true, the escape algorithm will not be applied, allowing HTML code inside all the cells. In this case, the user must ensure that the output code is valid. If only few cells have HTML code, wrap in a HtmlCell object instead. (Default = false)
  • continuation_row_alignment::Symbol: A symbol that defines the alignment of the cells in the continuation row. This row is printed if the table is vertically cropped. (Default = :r)
  • highlighters::Union{HtmlHighlighter, Tuple}: An instance of HtmlHighlighter or a tuple with a list of HTML highlighters (see the section HTML highlighters).
  • linebreaks::Bool: If true, \n will be replaced by <br>. (Default = false)
  • maximum_columns_width::String: A string with the maximum width of each columns. This string must contain a size that is valid in HTML. If it is not empty, each cell will have the following style:
    • "max-width": <value of maximum_column_width>
    • "overflow": "hidden"
    • "text-overflow": "ellipsis"
    • "white-space": "nowrap"
    If it is empty, no additional style is applied. (Default = "")
  • minify::Bool: If true, output will be displayed minified, i.e. without unnecessary indentation or newlines. (Default = false)
  • standalone::Bool: If true, a complete HTML page will be generated. Otherwise, only the content between the tags <table> and </table> will be printed (with the tags included). (Default = false)
  • vcrop_mode::Symbol: This variable defines the vertical crop behavior. If it is :bottom, the data, if required, will be cropped in the bottom. On the other hand, if it is :middle, the data will be cropped in the middle if necessary. (Default = :bottom)
  • table_div_class::String: The class name for the table div. It is only used if wrap_table_in_div is true. (Default = "")
  • table_class::String: The class name for the table. (Default = "")
  • table_style::Dict{String, String}: A dictionary containing the CSS properties and their values to be added to the table style. (Default = Dict{String, String}())
  • tf::HtmlTableFormat: An instance of the structure HtmlTableFormat that defines the general format of the HTML table.
  • top_left_str::String: String to be printed at the left position of the top bar. (Default = "")
  • top_left_str_decoration::HtmlDecoration: Decoration used to print the top-left string (see top_left_str). (Default = HtmlDecoration())
  • top_right_str::String: String to be printed at the right position of the top bar. Notice that this string will be replaced with the omitted cell summary if it must be displayed. (Default = "")
  • top_right_str_decoration::HtmlDecoration: Decoration used to print the top-right string (see top_right_str). (Default = HtmlDecoration())
  • wrap_table_in_div::Bool: If true, the table will be wrapped in a div. (Default: false)

HTML highlighters

A set of highlighters can be passed as a Tuple to the highlighters keyword. Each highlighter is an instance of the structure HtmlHighlighter. It contains the following two public fields:

  • f::Function: Function with the signature f(data, i, j) in which should return true if the element (i,j) in data must be highlighted, or false otherwise.
  • fd::Function: Function with the signature f(h, data, i, j) in which h is the highlighter. This function must return the HtmlDecoration to be applied to the cell that must be highlighted.

The function f has the following signature:

f(data, i, j)

in which data is a reference to the data that is being printed, and i and j are the element coordinates that are being tested. If this function returns true, the highlight style will be applied to the (i, j) element. Otherwise, the default style will be used.

If the function f returns true, the function fd(h, data, i, j) will be called and must return an element of type HtmlDecoration that contains the decoration to be applied to the cell.

A HTML highlighter can be constructed using two helpers:

HtmlHighlighter(f::Function, decoration::HtmlDecoration)

HtmlHighlighter(f::Function, fd::Function)

The first will apply a fixed decoration to the highlighted cell specified in decoration whereas the second let the user select the desired decoration by specifying the function fd.

Info

If only a single highlighter is wanted, it can be passed directly to the keyword highlighter without being inside a Tuple.

Note

If multiple highlighters are valid for the element (i, j), the applied style will be equal to the first match considering the order in the tuple highlighters.

Note

If the highlighters are used together with Formatters, the change in the format will not affect the parameter data passed to the highlighter function f. It will always receive the original, unformatted value.


LaTeX Back End

This back end produces LaTeX tables. This back end can be used by selecting backend = Val(:latex).

Keywords

  • body_hlines::Vector{Int}: A vector of Int indicating row numbers in which an additional horizontal line should be drawn after the row. Notice that numbers lower than 1 and equal or higher than the number of printed rows will be neglected. This vector will be appended to the one in hlines, but the indices here are related to the printed rows of the body. Thus, if 1 is added to body_hlines, a horizontal line will be drawn after the first data row. (Default = Int[])
  • highlighters::Union{LatexHighlighter, Tuple}: An instance of LatexHighlighter or a tuple with a list of LaTeX highlighters (see the section LaTeX highlighters).
  • hlines::Union{Nothing, Symbol, AbstractVector}: This variable controls where the horizontal lines will be drawn. It can be nothing, :all, :none or a vector of integers. (Default = nothing)
    • If it is nothing, which is the default, the configuration will be obtained from the table format in the variable tf (see LatexTableFormat).
    • If it is :all, all horizontal lines will be drawn.
    • If it is :none, no horizontal line will be drawn.
    • If it is a vector of integers, the horizontal lines will be drawn only after the rows in the vector. Notice that the top line will be drawn if 0 is in hlines, and the header and subheaders are considered as only 1 row. Furthermore, it is important to mention that the row number in this variable is related to the printed rows. Thus, it is affected by the option to suppress the header show_header. Finally, for convenience, the top and bottom lines can be drawn by adding the symbols :begin and :end to this vector, respectively, and the line after the header can be drawn by adding the symbol :header.
Info

The values of body_hlines will be appended to this vector. Thus, horizontal lines can be drawn even if hlines is :none.

  • label::AbstractString: The label of the table. If empty, no label will be added. (Default = "")
  • longtable_footer::Union{Nothing, AbstractString}: The string that will be drawn in the footer of the tables before a page break. This only works if table_type is :longtable. If it is nothing, no footer will be used. (Default = nothing)
  • row_number_alignment::Symbol: Select the alignment of the row number column (see the section Alignment). (Default = :r)
  • table_type::Union{Nothing, Symbol}: Select which LaTeX environment will be used to print the table. Currently supported options are :tabular for tabular or :longtable for longtable. If it is nothing the default option of the table format will be used. (Default = nothing)
  • tf::LatexTableFormat: An instance of the structure LatexTableFormat that defines the general format of the LaTeX table.
  • vlines::Union{Nothing, Symbol, AbstractVector}: This variable controls where the vertical lines will be drawn. It can be :all, :none or a vector of integers. In the first case (the default behavior), all vertical lines will be drawn. In the second case, no vertical line will be drawn. In the third case, the vertical lines will be drawn only after the columns in the vector. Notice that the left border will be drawn if 0 is in vlines. Furthermore, it is important to mention that the column number in this variable is related to the printed columns. Thus, it is affected by the columns added using the variable show_row_number. Finally, for convenience, the left and right border can be drawn by adding the symbols :begin and :end to this vector, respectively. (Default = :none)
  • wrap_table::Union{Nothing, String}: This variable controls whether to wrap the table in a environment defined by the variable wrap_table_environment. Defaults to true. When false, the printed table begins with \begin{tabular}. This option does not work with :longtable. If it is nothing the default option of the table format will be used. (Default = nothing)
  • wrap_table_environment::Union{Nothing, String}: Environment that will be used to wrap the table if the option wrap_table is true. If it is nothing the default option of the table format will be used. (Default = nothing)

LaTeX highlighters

A set of highlighters can be passed as a Tuple to the highlighters keyword. Each highlighter is an instance of the structure LatexHighlighter. It contains the following two fields:

  • f::Function: Function with the signature f(data, i, j) in which should return true if the element (i, j) in data must be highlighted, or false otherwise.
  • fd::Functions: A function with the signature f(data, i, j, str)::String in which data is the matrix, (i, j) is the element position in the table, and str is the data converted to string. This function must return a string that will be placed in the cell.

The function f has the following signature:

f(data, i, j)

in which data is a reference to the data that is being printed, i and j are the element coordinates that are being tested. If this function returns true, the highlight style will be applied to the (i, j) element. Otherwise, the default style will be used.

If the function f returns true, the function fd(data, i, j, str) will be called and must return the LaTeX string that will be placed in the cell.

There are two helpers that can be used to create LaTeX highlighters:

LatexHighlighter(f::Function, envs::Union{String,Vector{String}})

LatexHighlighter(f::Function, fd::Function)

The first will apply recursively all the LaTeX environments in envs to the highlighted text whereas the second let the user select the desired decoration by specifying the function fd.

Thus, for example:

LatexHighlighter((data, i, j) -> true, ["textbf", "small"])

will wrap all the cells in the table in the following environment:

\textbf{\small{<Cell text>}}
Info

If only a single highlighter is wanted, it can be passed directly to the keyword highlighter without being inside a Tuple.

Note

If multiple highlighters are valid for the element (i, j), the applied style will be equal to the first match considering the order in the tuple highlighters.

Note

If the highlighters are used together with Formatters, the change in the format will not affect the parameter data passed to the highlighter function f. It will always receive the original, unformatted value.


Markdown Back End

This back end produces Markdown tables. This back end can be used by selecting backend = Val(:markdown).

Keywords

  • allow_markdown_in_cells::Bool: By default, special markdown characters like *, _, ~, etc. are escaped in markdown back end to generate valid output. However, this algorithm blocks the usage of markdown code inside of the cells. If this keyword is true, the escape algorithm will not be applied, allowing markdown code inside all the cells. In this case, the user must ensure that the output code is valid. (Default = false)
  • highlighters::Union{MarkdownHighlighter, Tuple}: An instance of MarkdownHighlighter or a tuple with a list of Markdown highlighters (see the section Markdown Highlighters).

Markdown Highlighters

A set of highlighters can be passed as a Tuple to the highlighters keyword. Each highlighter is an instance of the structure MarkdownHighlighter. It contains the following two public fields:

  • f::Function: Function with the signature f(data, i, j) in which should return true if the element (i,j) in data must be highlighted, or false otherwise.
  • fd::Function: Function with the signature fd(h, data, i, j) in which h is the highlighter. This function must return the MarkdownDecoration to be applied to the cell that must be highlighted.

The function f has the following signature:

f(data, i, j)

in which data is a reference to the data that is being printed, and i and j are the element coordinates that are being tested. If this function returns true, the highlight style will be applied to the (i, j) element. Otherwise, the default style will be used.

If the function f returns true, the function fd(h, data, i, j) will be called and must return an element of type MarkdownDecoration that contains the decoration to be applied to the cell.

A markdown highlighter can be constructed using two helpers:

MarkdownHighlighter(f::Function, decoration::MarkdownDecoration)

MarkdownHighlighter(f::Function, fd::Function)

The first will apply a fixed decoration to the highlighted cell specified in decoration whereas the second let the user select the desired decoration by specifying the function fd.

Info

If only a single highlighter is wanted, it can be passed directly to the keyword highlighter without being inside a Tuple.

Note

If multiple highlighters are valid for the element (i, j), the applied style will be equal to the first match considering the order in the tuple highlighters.

Note

If the highlighters are used together with Formatters, the change in the format will not affect the parameter data passed to the highlighter function f. It will always receive the original, unformatted value.


Formatters

The keyword formatters can be used to pass functions to format the values in the columns. It must be a tuple of functions in which each function has the following signature:

f(v, i, j)

where v is the value in the cell, i is the row number, and j is the column number. Thus, it must return the formatted value of the cell (i, j) that has the value v. Notice that the returned value will be converted to string after using the function sprint.

This keyword can also be a single function, meaning that only one formatter is available, or nothing, meaning that no formatter will be used.

For example, if we want to multiply all values in odd rows of the column 2 by π, the formatter should look like:

formatters = (v, i, j) -> (j == 2 && isodd(i)) ? v * π : v

If multiple formatters are available, they will be applied in the same order as they are located in the tuple. Thus, for the following formatters:

formatters = (f1, f2, f3)

each element v in the table (i-th row and j-th column) will be formatted by:

v = f1(v,i,j)
v = f2(v,i,j)
v = f3(v,i,j)

Thus, the user must be ensure that the type of v between the calls are compatible.

PrettyTables.pretty_table_with_confMethod
pretty_table_with_conf(conf::PrettyTablesConf, args...; kwargs...) -> Nothing

Call pretty_table using the default configuration in conf. The args... and kwargs... can be the same as those passed to pretty_tables. Notice that all the configurations in kwargs... will overwrite the ones in conf.

The object conf can be created by the function set_pt_conf in which the keyword parameters can be any one supported by the function pretty_table as shown in the following.

source
PrettyTables.reset!Method
reset!(c::CustomTextCell)

Reset all fields in the custom text cell c.

This function is not required for the API. It is called before parsing the custom text cell.

source
PrettyTables.@html_cell_strMacro
@html_cell_str(str)

Create a table cell with HTML code.

Examples

julia> html_cell"<i>Italic text</i>"
HtmlCell{String}("<i>Italic text</i>")
source
PrettyTables.@latex_cell_strMacro
@latex_cell_str(str)

Create a table cell with LaTeX code.

Examples

julia> latex_cell"	extbf{Bold text}"
LatexCell{String}("\textbf{Bold text}")
source
PrettyTables.@ptMacro
@pt(expr...)

Pretty print tables in expr to stdout using the global configurations selected with the macro @ptconf.

Multiple tables can be printed by passing multiple expressions like:

@pt table1 table2 table3

The user can select the table header by passing the expression:

:header = [<Vector with the header>]

Notice that the header is valid only for the next printed table. Hence:

@pt :header = header1 table1 :header = header2 table2 table3

will print table1 using header1, table2 using header2, and table3 using the default header.

Info

When more than one table is passed to this macro, then multiple calls to pretty_table will occur. Hence, the cropping algorithm will behave exactly the same as printing the tables separately.

Examples

julia> @ptconf tf = tf_simple

julia> @pt :header = ["Time","Velocity"] [1:1:10 ones(10)] :header = ["Time","Position"] [1:1:10 1:1:10]

PrettyTables.@ptconfMacro
@ptconf(expr...)

Add configurations in expr to be used with the macro @pt.

The expression format must be:

keyword1 = value1 keyword2 = value2 ...

in which the keywords can be any other possible keyword that can be used in the function pretty_table.

Warning

If a keyword is not supported by the function pretty_table, then no error message is printed when calling @ptconf. However, an error will be thrown when @pt is called.
