There is also the issue where the scope attribute is not adequate for associating headers with data cells. The first instance that comes to mind is where you have a header which spans several columns. In this case, the scope attribute does not work properly (at least with jaws through 7.0). I have not tested with jaws 8.0 yet. > -----Original Message----- > From: wai-xtech-request@w3.org > [mailto:wai-xtech-request@w3.org] On Behalf Of Michael S Elledge > Sent: Tuesday, May 29, 2007 10:35 AM > To: Al Gilman > Cc: Laura Carlson; HTML WG; Judy Brewer; Patrick H.
