I'm working my way through Aaron Hillegass' Cocoa book, and where
he starts using the NSTableView class he points out the
cooperative relationship between a TableView and its DataSource.
Now being an awkward cuss I like to try figuring things out for
myself before reading the details in the book... (Coz in the
future the book might not cover my requirements and I need to get
in the habit of exploring for myself!) When I tried to use
TableView on its own I got completely messed because I didn't
know about dataSource... But I did see a reference to it ...
