You may also set the table view's delegate and implement tableView:willDisplayCell:forTableColumn:row: and modify the menu programmatically.

This all works up to this point, the menus populate for each row in the table view and I can make selections and update things in my controller. What I need to do is bind the individual enabled state of each menu item in the myOptions array. Binding the enabled state for the column does not work as it disables the entire menu. I've tried binding to both NSPopUpButtonCell and its NSMenuItem but nothing happens (all menu items remain enabled). Just to test I tried binding these two to arrangedObjects @count of the array controller (using NSNegateBoolean) but still nothing.

The transformer got called but I logged the value it was passing in and it's the array myOptions not the individual menu items. The validateMenuItem method worked for other UI NSPopUpMenus but not the ones in my tableview.
