title: QTableWidget how to have a cell selected for editing from code and/or with single click
body: <p>Two part question:
  I have a 10x10 QTableWidget with QTableWidgetItem in each cell.
  For some reason, clicking on a cell is not sufficient to edit it, I need to double-click the cell to enter it. </p>
  
  <ol>
  <li><p>Is there a way to change this behavior to single click </p></li>
  <li><p>Is there a way to have 2nd cell in 1st row selected and ready for editing by default when window is created?</p></li>
  </ol>
