So I am going for a custom looking NSTableView. I've already successfully subclassed `NSTableRowView` and `NSTextFieldCell` to achieve the look I'm going for, however I'm struggling of getting rid of the default styling for the header. I seem to be able to tweak its frame, however I'm not sure where the rest of the default styling is coming from.

As you see on the screenshot the red area is the increased frame of the `headerView`. I'm using its `CALayer` to set the colour, however how to change the contents inside is beyond me...

Here's what I'm doing in the `viewDidLoad` of my ViewController

```
override func viewDidLoad() {
    super.viewDidLoad()
    tableView.delegate = self
    tableView.dataSource = self
    tableView.wantsLayer = true
    tableView.headerView?.frame = NSMakeRect(0, 0, (tableView.headerView?.frame.width)!, 32.00)
    tableView.headerView?.wantsLayer = true
    tableView.headerView?.layer?.backgroundColor = NSColor.red.cgColor
}

```

I've also tried subclassing `NSTableHeaderView`, however this class seems to be extremely limited in terms of the customizations I can make...

Any help would be appreciated?
