I was thinking along slightly different lines. We have a customizable
<td> tag in HTML export already, but that customization isn't very
flexible. If we could have something like a <td> tag that can be set
from values in the table, or by Lisp code, then I think that would
solve my problems. It's important, however, that setting the export
tag must be local to the Org file so I can set it there instead of the
global .emacs.
