According to various web development forums, Web Designers around the world are still adhering to HTML tables for multicolumn layouts on web sites. As it is battled on more and more messageboards, the issues are between cross browser rendering and how Firefox, in most cases, does not render the CSS correctly, although some designers happy with Firefox complain that it is MS Explorer which causes the problem.
Until both browsers make it easy to render tableless CSS, designers promoting its benefits are not going to win the battle and tabled web sites will still prevail.
Some practice can be handled on CSS dominant web sites like CSSZenGarden.com and CSSBeauty.com.
The best advice I give to my web design readers is to practice on both Firefox and Internet Explorer.
