I've been looking everywhere for an extension that does this and can't find a
thing...surprisingly. If I knew JS enough I would build it myself but
sadly...it's a weak spot for me. Anyway, I'm wondering if anyone has an
extension, or could write an extension, for DW MX 2004 that after you to select
a cell in a data table as a header <th> (like it does now), you could then
select the <th> cell and then CTRL click all the other cells within the table
that need to have that <th> id attribute applied to it?

So I select a <td> to be a header changing it to : <th id="col1">...</th>, I
could then CTRL click that <th> and then all the other cells that should be
associated with it and then automatically make all of those <td> tags turn to:
<td headers="col1">...</td>. Right now this process is manual and although you
could use "scope=col" it's not well supported by screenreaders. An extension
that did this would make alot of developers needs to make accessible data
tables MUCH MUCH easier.

Thanks
