I am using jQuery DataTables plugins to create HTML tables and using the DataTables TableTools to generate the PDF of my Table data. It is working fine now I want to add the header and footer in the generated PDF. PDF generation code is written in ActonScript3 file using AlivePDF. So any one can help me on this how can I add header and footer code in my ActionScript3 file that usages AlivePDF. Below is the code :
package {

import flash.display.Sprite;

import flash.system.Security;
import flash.utils.*;

import flash.net.FileFilter;

If you want to hack the Actionscript to add an image, for example, as a header and a footer, you can check it here
It will be probably the easiest way if you don't know Actionscript
