Can't comment on performance, though. Its an inelegant solution.

Nested? You may be able to do this in pure CSS, without keeping a
depth counter at all.

It's an easy change.
function DrawSubTable($Set, $DepthCount = 0)
{
[..]
DrawSubTable($Set, $DepthCount + 1);
[..]
}
By providing a default value, all the calls to DrawSubTable() can
remain unchanged. You just have to modify its own calls to itself.
