You can also create a NSTableHeaderView object, initialize it with a frame(rect with height and width) and set that NSTableHeaderView object to your table view.

 NSTableHeaderView *tableHeaderView = [[NSTableHeaderView alloc] initWithFrame:NSMakeRect(0, 0, 120, 60)];
    [myTableView setHeaderView:tableHeaderView];
[tableHeaderView release];
