CSS or Tables?
 

Which do you use? I prefer to use tables, only because I can see them, and they are easier for me to manipulate.

I use both, but CSS Tableless sites are pretty nice.

Tables until IE becomes compatible with CSS.

Designing in tables is a hell lot easier than doing the same thing in CSS...but then by just modifying the css, u can change the complete structure of ur html file, it is amazingly powerful, basically it was created for making the presentation layer and contene layer seperate ;)
just check out www.csszengardens.com , and click on the different css links, and u will see some amazing layouts there !

agreed
 

Tables are very useful and reasonably easy to implement. By writting simple css scripts to go along with them you can have the best of both worlds, and save yourself a lot of code writting. Css scripts can be saved externally and loaded a single time, similar to javascripts, saving you load time and repeat loadings.

I prefer tables.

Very well said!
