<h2>Table Printing</h2>



This demo shows various ways of using the <b><i>new

</i></b> PrintOut class.  To understand the class you need to examine the demo examples

and the library <a href="%s">printout.py</a> module classes.

<p>

The initial class primarily contains a Table preview/printing class.  There is a lot of flexibility

in manipulating the placement, sizing, colours, alignment of the table text and cell background colors.

There are also a number of options for printing Header and Footer information on the page.

<p>

There is also a class to extract the parameters from a wxGrid and easily recreate a Table printout.

<p>

The data is printed from a list object containing the column and row values.  The label or table header

can be defined and will be repeated for all pages.

<p>

The correct "Total Page" does get calculated and used in the print out Footer.

<p>

There is still problems with the print framework to properly get the total pages in the preview unless

the program knows it before trying to parse through the available pages.  This will be fixed

when the framework allows for it.
