Discussion
This method is invoked after tableView(_:shouldShowMenuForRowAt:). It gives the developer the opportunity to exclude one of the commands—Copy or Paste—from the editing menu. For example, the user might have copied some cell content from one row but wants to paste into another row that doesn’t take the copied content. In a case like this, return false from this method.
