body: <p>How can I set QTableWidgetItem editor background color?</p>
  
  <p>I set item with not white background</p>
  
  <pre><code>setItem(row, column, itm);
  </code></pre>
  
  <p>While I am editing text of this item background is white. I need to make its background color as when it is not in editing state.</p>
