How can I define the alingment for a unique cell in a QTextTableCell ?

I've try with:

Qt Code:
  1. QTextCursor cur = celda.firstCursorPosition();
  2. cur.blockFormat().setAlignment( Qt::AlignRight );
  3. cur.insertText( "Total:" );
To copy to clipboard, switch view to plain text mode 
but it seems doest work... Even if tableFormat.setAlignment( Qt::AlignHCenter ); is set...

Any one could do that?

Thanks in advance...
