Nstableview user group

I am creating a table view based on the view, and I'm having trouble creating a custom group. I want to have text in my group, and the default behavior that Apple provides is great, but I need to change the color and appearance of the actual string. I have subclassed NSTableRowViewand it works, but unfortunately not very well. In particular, when he begins to swim, I did not understand how to change the alpha representation without changing the alpha text as well.

You can load in a custom Row in a Table View delegate using the tableView: rowViewForRow: method. Just return a copy of it right there.
