Having said all that, I must also say this it depends on the CSS being used. After tossing in the towel on the css I found at http://www.bluerobot.com/web/layouts/
because of the problems described here (I could get it to work in MSIE 5.1, OmniWeb 4.1 (oddly), but not Mozilla 1.0Rrc3), I started working with the A List Apart approach (http://www.alistapart.com
) to do table-less layout. Their css works fine when served by Conversant, in all (OS X) browsers.
