 179 <h2>Table Printing</h2>
 180
 181 This demo shows various ways of using the <b><i>new
 182 </i></b> PrintOut class.  To understand the class you need to examine the demo examples
 183 and the library <a href="%s">printout.py</a> module classes.
 184 <p>
 185 The initial class primarily contains a Table preview/printing class.  There is a lot of flexibility
 186 in manipulating the placement, sizing, colours, alignment of the table text and cell background colors.
 187 There are also a number of options for printing Header and Footer information on the page.
 188 <p>
 189 There is also a class to extract the parameters from a wxGrid and easily recreate a Table printout.
 190 <p>
 191 The data is printed from a list object containing the column and row values.  The label or table header
 192 can be defined and will be repeated for all pages.
 193 <p>
 194 The correct "Total Page" does get calculated and used in the print out Footer.
 195 <p>
 196 There is still problems with the print framework to properly get the total pages in the preview unless
 197 the program knows it before trying to parse through the available pages.  This will be fixed
 198 when the framework allows for it.
