i've got a bound table view. is it possible to use a different value transformer based on which row of the table is being displayed/ edited? and if so, how?

Yes, you can. The formatter is a property of the cell, and not the column, per se. You need an object that is the tableview's delegate, then implement -tableView:willDisplayCell:forTableColumn:row:. NSCell has a -setFormatter: method for your convenience. I have used this successfully without error, but I haven't performance tested it. I don't suspect that it is much slower.
