NSTableHeaderCells behave a bit differently than other cells.
Normally -[NSCell highlight:withFrame:inView:] just sets the
isHighlighted flag (and probably marks the view as needing display).
NSTableHeaderCell, on the other hand, performs the drawing
immediately.  So -drawWithFrame:inView: is used to draw an unselected
table header cell, and -highlight:withFrame:inView: is used to draw a
selected table header cell.

I think this goes for other cells too. I had to use these two methods in the drawRect method when writing a custom ListView control where I used a TextFieldCell subclass.
