Hello all, At today's teleconference [1], we talked about support for THEAD in HTML user agents. The context: Do user agents support the rendering where THEAD rows are fixed on the screen while other data cells are scrolled by. To test this, I have published a test table [2] that uses THEAD for the first row (the one starting "Rows"). My results in my Linux environment are that no user agent I have supports this, including: Lynx 2.8.4rel.1 [Text browser] w3m 0.3 [Text browser that supports tables somewhat] Mozilla 0.9.9 Netscape 7.0 Preview release 1 Amaya 5.3 (18 Dec 2001) Opera 6.0 Preview 6 Konqueror 2.2.2 (KDE 2.2.2) Dillo 0.6.4 Untested: Galeon (Not working on my machine since I installed Netscape 7) Skipstone (I just installed to test this one, but it crashes). Perhaps I missed some UA configurations that would cause these user agents to keep THEAD frozen in place, but I didn't find any settings. I also tried using 'position:fixed' on the THEAD element for user agents that support CSS fixed positioning. However, since fixed positioning pulls an element out of the flow, the result (at least on Opera) is that the THEAD row is not formatted the same as the other (TBODY) rows. So while the THEAD row remains fixed on the screen, the cells in the other rows don't line up with it, so this approach is not helpful. _ Ian [1] http://lists.w3.org/Archives/Public/w3c-wai-ua/2002AprJun/0192 [2] http://www.w3.org/WAI/UA/2002/06/thead-test -- Ian Jacobs (ij@w3.org) http://www.w3.org/People/Jacobs Tel: +1 718 260-9447
