Here's an example:

<STYLE>
TD:hover { color: green }
</STYLE >
<TABLE border="1">
<TR><TD>1 <TD>2 <TD>3
<TR><TD>4 <TD rowspan="2">5 <TD>6
<TR><TD colspan="2">7 <TD>9
</TABLE>

In this example, cell 5 and cell 7 actually overlap and share a position in the grid.  You can see that hit testing works properly and gives cell 7 precedence over cell 5 (e.g., if you're in overlapping background areas of the cell, then cell 7 wins).
