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.
