Re: Newbie problem with protocol

First off, you don't need #import <AppKit/NSTableView.h> because it's
redundant.

Second, there is no protocol called NSTableDataSource. The docs say that it
is an informal protocol, not a formal protocol. So take out
<NSTableDataSource> and be sure to implement the methods the docs tell you
to, and you'll be fine.

On your computer, the documentation for this is located at:
file:///Developer/Documentation/Cocoa/TasksAndConcepts/ProgrammingTopics/Tab
leView/index.html
