Unable to add/remove row/columns in IE8

Clicking any of the add/remove buttons for rows/columns appears to be busted in IE8.
I'm not going to argue on this. Just one thing to notice is that in most software, most functions are going to be private, I would expect. So... to have most functions begin with an underscore is a bit ugly. But I can the beauty of it, as well. It makes a clear distinction between private and public, which can't be accidentally stepped over, because you can't possibly miss that underscore.
