Hi,

So the problem is due to lexical binding (I am using emacs 25 devel branch).
The following variables can't be dynamically bound anymore in ox-html:
row-number, rowgroup-number, start-rowgroup-p, end-rowgroup-p,
top-row-p, bottom-row-p
.
There are 2 options :
- declare them with defvar
- pass them to eval as an environment.
Here is a patch for the second option, but I wonder if the first one
wouldn't be better.

        ;; End a rowgroup?
        (when end-rowgroup-p (cdr rowgroup-tags))))))

Best regards,
