title: Painting QPixmap in the center of QTableView cell
body: <p>I have a QTableView that works very well, the first column holds some thumbnails, in each cell of this column the thumbnails are vertically centered, but not horizontally centered.</p>
  
  <p>Do I really need to use a delegate?
  If yes, How to center them horizontally using QStyledItemDelegate?</p>
