A second try at excel-like table selection.

Click and drag to make selection.

Issues: select box is obviously behind the table cells, so looks a little odd. Now I can't bind right-click to the select box since it's behind the table. I also haven't accounted for negative distance selection (dragging the selection to the left from the starting point), but that wouldn't be too hard to add. If you leave the confines of the table while dragging it produces unexpected behavior.

Big issue: Carl noticed this is only working in FireFox. I suspect it's a plugin I'm using to suppress drag from selecting the table text, the plugin claims it works in all browsers, but it might not be the case, or it might be conflicting with the rest of my script. So, if you want to see this working, open it in FireFox.
