None of Opera 9.02, Firefox 2.0, IE7 and Safari 2.0.4 implement

least agree on what to do with it: they treat it like colspan=1.
I suggest that only positive integers be conforming and that
non-conforming values be treated as 1.

I know browser vendors have had a long time to implement this, but
still, I think giving up on it would be a shame. The number of rows or
columns in a table is often rather expensive to calculate ahead of
time. As long as this has to be done to calculate the rowspan= or
colspan= of header cells, this can substantially increase the time an
application takes to generate a table. For the browser to interpret
colspan=0 or rowspan=0 instead would both make life easier for
application authors, and make such pages faster overall.
