title: EPPlus - AutoFitColumns() method fails when a column has merged cells
body: <p>I was wondering if anyone has come up with a workaround to this problem.  I've noticed that the AutoFitColumns() method is failing on columns with merged cells.  I've included a basic code example below:</p>
  
  <pre><code>var cellRange = worksheet.Cells[1, column, 2, column];
  cells.Merge = true;
  cells.Style.HorizontalAlignment = OfficeOpenXml.Style.ExcelHorizontalAlignment.Center;
  cells.Value = "Some Text Goes Here";
  worksheet.Cells.AutoFitColumns();
  </code></pre>
  
  <p>The resulting worksheet will have the cells in rows 1 and 2 merged (correctly) for the column in the column variable, but that particular cell is disregarded by the AutoFitColumns() method.</p>
  
  <p>Any help would be appreciated.</p>
