Tom, I don't think your example is related to this task, but rather FS#2719
You would assume the empty cell would show because we have "empty-cells: show" for tables. But as the whole *row* is empty it might be that browsers decide to not display it. And I think that's good, because to have an empty row in the first place doesn't make any sense, semantically. So, that should rather be fixed together with FS#2719
and no tables should be used at all. Another option would be to say the content should be a new line, which should really be a `<br />`.
