NAME

    Term::Table - Format a header and rows into a table

DESCRIPTION

    This is used by some failing tests to provide diagnostics about what
    has gone wrong. This module is able to format rows of data into tables.

SYNOPSIS

        use Term::Table;
    
        my $table = Term::Table->new(
            max_width      => 80,    # Defaults to terminal size
            pad            => 4,     # Extra padding between table and max-width (defaults to 4)
            allow_overflow => 0,     # Default is 0, when off an exception will be thrown if the table is too big
            collapse       => 1,     # Do not show empty columns
    
            header => ['name', 'age', 'hair color'],
            rows   => [
                ['Fred Flintstone',  2000000, 'black'],
                ['Wilma Flintstone', 1999995, 'red'],
                ...
            ],
        );
    
        say $_ for $table->render;

    This prints a table like this:

        +------------------+---------+------------+
        | name             | age     | hair color |
        +------------------+---------+------------+
        | Fred Flintstone  | 2000000 | black      |
        | Wilma Flintstone | 1999995 | red        |
        | ...              | ...     | ...        |
        +------------------+---------+------------+

INTERFACE

        use Term::Table;
        my $table = Term::Table->new(...);

 OPTIONS

    header => [ ... ]

      If you want a header specify it here. This takes an arrayref with
      each columns heading.

    rows => [ [...], [...], ... ]

      This should be an arrayref containing an arrayref per row.

    collapse => $bool

      Use this if you want to hide empty columns, that is any column that
      has no data in any row. Having a header for the column will not
      effect collapse.

    max_width => $num

      Set the maximum width of the table, the table may not be this big,
      but it will be no bigger. If none is specified it will attempt to
      find the width of your terminal and use that, otherwise it falls back
      to the terminal width or 80.

    pad => $num

      Defaults to 4, extra padding for row width calculations. Default is
      for legacy support. Set this to 0 to turn padding off.

    allow_overflow => $bool

      Defaults to 0. If this is off then an exception will be thrown if the
      table cannot be made to fit inside the max-width. If this is set to 1
      then the table will be rendered anyway, larger than max-width, if it
      is not possible to stay within the max-width. In other words this
      turns max-width from a hard-limit to a soft recommendation.

    sanitize => $bool

      This will sanitize all the data in the table such that newlines,
      control characters, and all whitespace except for ASCII 20 ' ' are
      replaced with escape sequences. This prevents newlines, tabs, and
      similar whitespace from disrupting the table.

      Note: newlines are marked as \n, but a newline is also inserted into
      the data so that it typically displays in a way that is useful to
      humans.

      Example:

          my $field = "foo\nbar\nbaz\n";
      
          print join "\n" => table(
              sanitize => 1,
              rows => [
                  [$field,      'col2'     ],
                  ['row2 col1', 'row2 col2']
              ]
          );

      Prints:

          +-----------------+-----------+
          | foo\n           | col2      |
          | bar\n           |           |
          | baz\n           |           |
          |                 |           |
          | row2 col1       | row2 col2 |
          +-----------------+-----------+

      So it marks the newlines by inserting the escape sequence, but it
      also shows the data across as many lines as it would normally
      display.

    mark_tail => $bool

      This will replace the last whitespace character of any trailing
      whitespace with its escape sequence. This makes it easier to notice
      trailing whitespace when comparing values.

    show_header => $bool

      Set this to false to hide the header. This defaults to true if the
      header is set, false if no header is provided.

    auto_columns => $bool

      Set this to true to automatically add columns that are not named in
      the header. This defaults to false if a header is provided, and
      defaults to true when there is no header.

    no_collapse => [ $col_num_a, $col_num_b, ... ]

    no_collapse => [ $col_name_a, $col_name_b, ... ]

    no_collapse => { $col_num_a => 1, $col_num_b => 1, ... }

    no_collapse => { $col_name_a => 1, $col_name_b => 1, ... }

      Specify (by number and/or name) columns that should not be removed
      when empty. The 'name' form only works when a header is specified.
      There is currently no protection to insure that names you specify are
      actually in the header, invalid names are ignored, patches to fix
      this will be happily accepted.

NOTE ON UNICODE/WIDE CHARACTERS

    Some unicode characters, such as 婧 (U+5A67) are wider than others.
    These will render just fine if you use utf8; as necessary, and
    Unicode::GCString is installed, however if the module is not installed
    there will be anomalies in the table:

        +-----+-----+---+
        | a   | b   | c |
        +-----+-----+---+
        | 婧 | x   | y |
        | x   | y   | z |
        | x   | 婧 | z |
        +-----+-----+---+
