Is there a way to detect the height of a TD tag?

In recent browsers only, you can get the height of a table CELL (not a
tag - tags don't have a height).

Given the following cell:
<td id="whatever">...</td>

<script type="text/javascript">
myVar = document.getElementById?document.getElementById
("whatever").getAttribute("height"):0;
</script>

Browsers (older ones, like NN4) that do not support
document.getElementById would get 0 as the value.

<script type="text/javascript">

</script>

but here, there is no height attribute defined for the "whatever" cell,
so myVar will hold null. Height is not a valid attribute in strict DTD
anyway.

OTOH, document.getElementById("whatever").offsetHeight will return the
general pixel height of the cell.

Tested and working in Opera 7.20, Mozilla 1.5RC2, MSIE 6 and NS 7.1.
