The NSTableDataSource protocol is an informal protocol. You need only
implement the methods and should not (in this case cannot) adopt the
protocol in the declaration of the class as you have shown below. There
is also no need to import the table view header file separatly, it's
part of the heders you import when importing Cocoa.h.
