No, by definition   means the NO-BREAK SPACE character, which is
like the SPACE but probihits line breaks before and after (which means
nothing here) and, as a strange effect due to oddities in web browsers,
partly described in HTML specs, acts as nonempty content in a table
cell.

So it's more or less a hack but it works, mostly. It causes trouble if
you want to make the cell very small in either direction, since NO-BREAK
SPACE has some definite width and some height.

It's a good idea to consider whether it would be better to insert some
other content into the cell, such as "N/A" or "0" or "–" or
whatever constitutes a useful indication or hint. After all, the user
might not immediately realize _why_ the cell is empty and might even
assume that it might be an error.
