title: How to set a data type for a column with ClosedXML?
body: <p>I see a lot of examples in documentation where data type for a cell is set:</p>
  
  <pre><code>ws.Cell(1, 1).SetDataType(XLCellValues.Text);
  </code></pre>
  
  <p>But when I try to set a data type for a column:</p>
  
  <pre><code>ws.Column(1).SetDataType(XLCellValues.Text)
  </code></pre>
  
  <p>ClosedXML generates a 5MB file and data type is not actually set.</p>
  
  <p>This operation works as expected in Excel (right-click on the column header, format cells, ...).</p>
  
  <p>If it is a limitation of ClosedXML, can it be easily fixed, or is there a workaround?</p>
