This gives the following error:

Can anyone type in the "theory" behind the ComboBoxTableCell, and list the parts necessary to accomoplish this. All I want to do is to change the value of the cell extracted from a PhoneList in another file.
`final TableColumn<Book, String> whoCol = new TableColumn<>("Who to");

This works - @James_D thank you for your aid - you sent me in the right direction
