title: EPPlus Print Area - column definition
body: <p>I want to define a list of columns as an Excel PrintArea (by EPPlus, c#). I can define interval (first and last column of area) but I don't know how to define separate columns (for instance: A, C, F, G).</p>
  
  <p>I can set interval like this:</p>
  
  <pre><code>listSheet.PrinterSettings.PrintArea = listSheet.Cells["A,G"];
  </code></pre>
