What you are doing will not work.
/* Gets and sets the headerCell associated with this NSTableColumn. 'cell' must be non nil, and should be a member of the NSTableHeaderCell class. The 'headerCell' is a strong reference, and will be retained.
*/
- (void)setHeaderCell:(NSCell *)cell;
- (id)headerCell;
You have to create an NSTableHeaderCell subclass. Even then, you may have to subclass NSTableHeaderView to get it to work like a button with a button in it (header's are essentially buttons).
