I need to get the entire site into a 3 cell table. The left and right sides being expandable with the page (I already know how to do this if I make a page from scratch) and the store staying in the center cell.

Does anyone know where the MAIN of all main tables is in the code? Or where I would need to go so I could add this table around/outside the store? Im very good as far as basic html and templating goes, but I dont know a lot about PHP.

Thanks for any help :)
