The problem is that it's not, technically, an error. In fact the HTML
4.01 spec goes as far as to say that for rows with less than the
maximum number of columns you should pad the end of the row with empty
cells. [0]

Anything checking your HTML has no way to know whether you intended
that or not. I'd suggest that the easiest way is to use a stylesheet
something like this:

td { border-width: 1px;
     border-style: solid; }

which should show you what the table looks like (not that I've tested
it and it's obviously browser dependant).

cheers
