Answer 1

I share this code for Swift 4.

func tableView(_ tableView: NSTableView, viewFor tableColumn: NSTableColumn?, row: Int) -> NSView? {
   ........
   but.action =  #selector(ViewController.buttonAction)
   .........
}

@objc func buttonAction(but: NSButton){
   let tablerow: NSTableRowView = but.superview?.superview as! NSTableRowView;
   let index = table?.row(for: tablerow);
   print("\(index));
}
