Putting the ordering triangles in table columns (NSTableView->General)

Put this somewhere (maybe in your mouseDownInHeaderOfTableColumn or didClickTableColumn:

    NSImage *indicatorImage;
    if (sortAscending) {
        sort your data ascending
        indicatorImage = [NSImage imageNamed: @"NSAscendingSortIndicator"];
    } else {
        sort your data descending
        indicatorImage = [NSImage imageNamed: @"NSDescendingSortIndicator"];
    }
    sortAscending = !sortAscending;

    [tableView setIndicatorImage: indicatorImage
                   inTableColumn: tableColumn];

    [tableView reloadData];
