  for (int row = 0; row < _flex.Rows.Count; row++)
  {
    // get cell content
    string text = _flex.GetDataDisplay(row, col);

    // check that the cell contains html
    if (!string.IsNullOrEmpty(text) &&
         text.StartsWith("<html>"))
    {
      // measure width needed to render the Html
      _superLabel.Text = text;
      int width = _superLabel.Measure().Width;

      // save maximum width
      if (width > maxWidth)
        maxWidth = width;
