I am in complete agreement with Dhej, tables are only to be used for tables. Use css for layout.

Great book: 'Designing with web standards' Read it

If your gonna stick with using a table, here is something I have noticed...
In IE, changing the "Text Size" setting under the "View" menue will affect
tables used for layout, especially when images are involved. Try looking at
the web page with different text sizes.
