Subclasses of the NSTableHeaderCell class can override the drawInterior(withFrame:in:), edit(withFrame:in:editor:delegate:event:), and highlight(_:withFrame:in:) methods to change the way headers appear. This specific subclass is responsible for drawing the sort indicators. See the NSCell class specification for information on overriding these methods.
