解决方法
一种方法,在NSTableViewDelegate的viewForTableColumn -function中:
if tableColumn!.identifier == "description" { let cell = NSTableHeaderCell() cell.title = "New Title" cell.backgroundColor = NSColor.redColor() cell.drawsBackground = true cell.bordered = false cell.font = NSFont(name: "Helvetica",size: 16) tableColumn!.headerCell = cell }
