DESCRIPTION

This is the theme interface (or Moose role), that all theme objects must use.

CREATING THEMES

A theme is defined as an hash reference containing all options:

  # a very ugly theme...
  my $theme = { 
              'Duisburg' => {
                  'HEADER_FONT_STYLE'  => 'sc',
                  'HEADER_FONT_COLOR'  => 'white',
                  'HEADER_BG_COLOR'    => 'blue',
                  'HEADER_CENTERED'    => 1,
                  'DATA_BG_COLOR_ODD'  => 'blue!30',
                  'DATA_BG_COLOR_EVEN' => 'blue!10',
                  'CAPTION_FONT_STYLE' => 'sc',
                  'VERTICAL_LINES'     => [ 1, 2, 1 ],
                  'HORIZONTAL_LINES'   => [ 1, 2, 0 ],
                  'EXTRA_ROW_HEIGHT'   => '2pt',
                  'BOOKTABS'           => 0,
              },
          };

Fonts

HEADER_FONT_STYLE, CAPTION_FONT_STYLE. Valid values are bf (bold), it (italics), sc (caps) and tt (typewriter). When this option is undef, then header (or caption, respectively) is written in normal font.

Colors

HEADER_FONT_COLOR can be used to specify a different font color for the header. Requires the xcolor LaTeX package.

Set HEADER_BG_COLOR to use a background color in the header, DATA_BG_COLOR_EVEN and DATA_BG_COLOR_ODD for even and odd data rows. Requires the colortbl and the xcolor LaTeX package.

You can define colors with DEFINE_COLORS, for example:

  'DEFINE_COLORS'      => '\definecolor{latextbl}{RGB}{78,130,190}',

Lines

VERTICAL_LINES, HORIZONTAL_LINES. A reference to an array with three integers, e.g. [ 1, 2, 0 ]. The first integer defines the number of outer lines. The second the number of lines after the header and after the first column. The third is the number of inner lines. For example Dresden is defined as:

  'Dresden' => {
      ...  
      'VERTICAL_LINES'     => [ 1, 2, 1 ],
      'HORIZONTAL_LINES'   => [ 1, 2, 0 ],
  }

The first integers define one outer line - vertical and horizontal. So a box is drawn around the table. The second integers define two lines between header and table and two vertical lines between first and second column. And finally the third integers define that columns are separated by a single vertical line whereas rows are not separated by horizontal lines.

Misc

EXTRA_ROW_HEIGHT

Will set \extrarowheight in the floating environment. Requires the array LaTeX package.

HEADER_CENTERED

Valid values are 0 (not centered) or 1 (centered).

BOOKTABS

Use the booktabs LaTeX package for "Publication quality tables". Instead of \hline, LaTeX::Table then uses \toprule, \midrule and \bottomrule. 0 (don't use this package) or 1 (use it).

You can either quickly add themes after initiation of an LaTeX::Table:

  $table->set_custom_themes($theme);

Or, you can build a "THEME MODULE" and extend the list of predefined themes.

THEME MODULE

Now, to build a theme that you can easily load, take the "SYNOPSIS" template, change it and then make it accessible in LaTeX::Table by saving it under the LaTeX::Table::Themes::* namespace. Alternatively, you can use the search_path() method to add custom paths. See "SYNOPSIS". If your theme looks nice, please contribute it.
