Hiding NSTableView header?
In Interface Builder, select the table view, open the attributes inspector (alt-command-4), and uncheck the "Headers" checkbox in the "Columns" section.
You can also set the headerView programmatically without subclassing
[tableView setHeaderView:nil];
To do this programmatically, you can subclass NSTableView (or any NSTableView child class) and return nil for the headerView variable:
@interface AppTableView : NSTableView {
}
@end
@implementation AppTableView
- (NSTableHeaderView *)headerView{
return nil;
}
@end
Swift 5
tableView.headerView = nil
