Once you make your syntax perfect, be sure to add a DOCTYPE to your HTML 
output (preferably something like XHTML 1.0 Strict). This will tell smart 
browsers like Firefox to not try and work around possible mistakes.

Another option you should test is not using tables at all. I don't know about 
the performance of very large pages, but CSS _may_ be faster then tables 
(although it could also depend on the browser).
