Top add-on in NSTableView Cell

Question

I want to add some space on top to NSTextFieldCell, I searched, I found a way with a subclass. But this way my touch event for the table does not work. if I use TouchFieldCell touch events, then also I can not find the real data according to the cell to delete and other actions.

So, it would be better if there is a possible way to do this. Thank you very much.
