title: pyqt: copy paste whole row from QtTablewidget to another QTablewidget
body: <p>I'm discovering pyqt and I'm struggling to copy paste a whole row from one tablewidget to another. I've been able to copy paste single items but I don't know how to proceed for a whole row...</p>
  <p>My code:</p>
  <pre><code>        for a in [self.tableWidget.selectedItems()[2]]:
              cloned_item = a.clone()
              self.tableWidget_2.setColumnCount(5)
              self.tableWidget_2.insertRow(0)
              self.tableWidget_2.setItem(0,0,cloned_item)
  </code></pre>
