title: Creating popup menu in Qt for QTableView
body: <p>I have a <code>QTableView</code> in the main UI of my program. I'd like to show popup menu when user right clicks on the cells of the table and take appropriate action when an option is selected from the menu.   </p>
  
  <p>I am using Qt Creator 1 (Qt version 4.5). How can I do that?</p>
