Hi! Looks like a page layout. It's a bad idea to use tables, as anyone will tell you. The best way would be to style it using .css, so I've transformed your 'table' with .css. Here it is. It's a centred "wrapper" with nested divs. You will have to adjust it according to your requirements, of course.
Cheers!
