Insert NSTableView Content View

Question

I want to insert the contents of an NSTableView so that there is a space between the top view of the table and the first cell.

On iOS, this is easy with a UITableView - achieved with setContentInset :.

Answer 1

Include headers and replace the header view with your own subclass. Override it with -drawRect: draw only your background color. Also, override -headerRectOfColumn: to prevent drawing any column heading. I'm not sure if this will prevent the columns from being dragged or sorted, but I'm betting it does.

  if (row == 0) {
    return normalRowHeight + topPadding;
  } else {
    return normalRowHeight;
  }
}
