title: how do i place QTableWidgetItem Icon in center of cell
body: <p>i want a table cell to have just an icon without any text.</p>
  
  <p>i see the <code>QTableWidgetItem</code> class has a method to align the text (<code>int QTableWidgetItem::textAlignment () const</code>)</p>
  
  <p>i find no way to adjust the placement of the icon (which seems to get stuck on the left -- even where there is no text in the cell)</p>
  
  <p>look at the Status and Energy columns.</p>
