sortable_tables.js resizing width of columns

[Rainy]

Hello, sortable_tables.js is very nice and easy and I'd very much like
to use it, but there is a slight cosmetic problem - when you click on
the column, it's resized a little bit, to accomodate the arrow, which
I think doesn't look very nice. It may be a nitpick, but is there a
way to avoid this? I was just thinking right now as I write, maybe
include a blank space placeholder and delete it & replace with the
arrow? That should be easy, I'll go try it. If anyone solved this
please post.
