Thank you for the suggestion.

I ran a quick test with TeX4ht, which also produced TD elements only - 
at least for the example which I tried.

However, the screen reader with which I evaluated the output recognized 
the table. On the other hand, it didn't read the header cells while 
navigating among the body cells. This is unsurprising, of course, as the 
headers weren't designated as such.

Thus the results were somewhat better with TeX4ht, but it still seems to 
me that having means of marking up header cells for purposes of HTML 
conversion would be useful. I don't remember whether tagged PDF (at 
least with the standardized element set) distinguishes between header 
and body cells in a table.
