如何更改NSTableColumn的背景？

Question

I need to change the background of specific columns in my NSTableView (on mac).

Should I change it at column level or cell level?

thanks

You can change the color for each of the cells in that column. Something kind of like:

- (NSView*)tableView:(NSTableView*)tableView viewForTableColumn:(NSTableColumn*)tableColumn
              row:(NSInteger)row
{
    //make cell
    ...
    if([tableColumn.identifier isEqual:@(0))
    {
        cellView.drawsBackground = YES;
        cellView.backgroundColor = [NSColor lightGrayColor];
    }
}
