=head1 DESCRIPTION
This class is a utility for use with the PDF::API2 module from CPAN.
It can be used to display text data in a table layout within the PDF.
The text data must be in a 2d array (such as returned by a DBI statement handle fetchall_arrayref() call).
The PDF::Table will automatically add as many new pages as necessary to display all of the data.
Various layout properties, such as font, font size, and cell padding and background color can be specified for each column and/or for even/odd rows.
Also a (non)repeated header row with different layout properties can be specified.

=item HEADER ROW PROPERTIES
If the 'header_props' parameter is used, it should be a hashref.
If the 'header_props' parameter is used, it should be a hashref.
It is your choice if it will be anonymous inline hash or predefined one.
Also as you can see there is no data variable for the content because the module asumes that the first table row will become the header row. It will copy this row and put it on every new page if 'repeat' param is set.

......
=item COLUMN PROPERTIES
If the 'column_props' parameter is used, it should be an arrayref of hashrefs,
with one hashref for each column of the table. The columns are counted from left to right so the hash reference at $col_props[0] will hold properties for the first column from left to right.
If the 'column_props' parameter is used, it should be an arrayref of hashrefs,
