I don't think NSTableView has got anything that will help with this. The nearest you're going to get is column reordering (with columns you've created in code), but this means you'll need to have column header shown to enable dragging, and dragging the header will re-order every row.

Either the parent view or the parent view's (view or window) controller can KVO-observe the "colors" property in the data model, and adjust the contents of the view as necessary.
