I was playing around with this a couple of days ago, and got to exactly this point. The next step was to capture the relevant portion of the TableViewHeader and use it as the 'representation'.
Some people might want some transitions/animations when dragging columns around, but IMHO a simple highlighted column, or even a thicker vertical dividing line between the columns would be enough to start with. Anyway, it looks like you are progressing nicely, so I'll sit back and wait to see how things turn out!
