I do believe you have set to record for the longest subject line (yet, and
hopefully for all time) on this mailing list.

Oddly enough, my current exercise is an attempt to render a view of a OLAP
cube into HTML, so I am slamming into the limitations of current
HTML/CSS/Javascript quite a bit (as well as the differences between browser
implementations).  I can indeed see a need for abstracting the
representation of row and column headers beyond what is currently present in
the HTML standard and implementations.  At present I do not have an opinion
on what that abstraction should look like.  (I will, but not yet.)

That said, my immediate reactions in reading the above:

   1. I would prefer to add a new attribute to the existing <table> tag
   over defining a new tag.
   2. Generating three round trips to the server to populate a table is
   not optimal.  My interest would be in populating the table with a single
   round trip (possibly also used for other purposes) using the DOM and
   Javascript.  Otherwise you want an inline HTML variant.
   3. Is this really the right model?

Guess I just do not see this as compelling or necessarily the right model.
