title: How to highlight a row in QTableWidget?
body: <p>I'm having a <code>QTableWidget</code> with 9000 data. I can search data from the table, like, if I search for '10', whole data starting with '10' will be displayed.
  Now I need to highlight the first row, since it shows the accurate search result.</p>
  
  <p>I'm using: </p>
  
  <pre><code>ui-&gt;tableWidget-&gt;setSelectionBehavior(QAbstractItemView::SelectRows); 
  </code></pre>
  
  <p>for highlighting the selected row.</p>
  
  <p>How can I highlight the first row of table?</p>
