Get button's row in view based table

Question

How do you get the row for a button in a view based table when you click the button? The row is not selected when the button is clicked, but I found that if you log sender.superview.superview in the button's action method, I get: NSTableRowView: 0x1001b3a90 - row: 2. So, the row is there in the log, but I don't know how to get at it programmatically. I have the button's action method in a subclass of NSTableCellView.

In Swift 5.1 -

func tableView(_ tableView: NSTableView, viewFor tableColumn: NSTableColumn?, row: Int) -> NSView? {

 if let checkBoxCell =  tableView.makeView(withIdentifier:NSUserInterfaceItemIdentifier(rawValue: "<ColumnIdentifier>"), owner: self) as! NSButton? {
                checkBoxCell.tag = row;
                checkBoxCell.target = self;
                checkBoxCell.action =  #selector(TableViewService.checkBoxAction)
                return checkBoxCell
            }
return nil

}

@objc func checkBoxAction(button:NSButton){

        print(button.tag);
    }

-[NSTableView rowForView:] says this in its documentation:

This is typically needed in the action method for an NSButton (or NSControl) to find out what row (and column) the action should be performed on.
