@Override

   Object element = cell.getElement();

   StyledString styledString = getStyledText(element, cell.getColumnIndex());
   String newText = styledString.toString();

   StyleRange[] oldStyleRanges = cell.getStyleRanges();
   StyleRange[] newStyleRanges = isOwnerDrawEnabled() ? styledString.getStyleRanges() : null;

   if (!Arrays.equals(oldStyleRanges, newStyleRanges)) {
      cell.setStyleRanges(newStyleRanges);
   }

   cell.setText(newText);
   cell.setImage(getColumnImage(element, cell.getColumnIndex()));
   cell.setFont(getFont(element, cell.getColumnIndex()));
   cell.setForeground(getForeground(element, cell.getColumnIndex()));
   cell.setBackground(getBackground(element, cell.getColumnIndex()));

   // no super call required. changes on item will trigger the refresh.
