title: EPPlus AutoFitColumns not working
body: <p>Seems to be a few folks with this problem, and usually it's solved because they haven't loaded data yet. I've loaded my data, but the Autofit is still not working. </p>
  
  <pre><code>Dim fi As New FileInfo(fileDialog.FileName)
  Dim pck As New ExcelPackage(fi)
  
  Dim epWs As ExcelWorksheet = pck.Workbook.Worksheets.Add("My Sheet")
  epWs.Cells("A1").LoadFromDataTable(data, True)
  
  With epWs.Cells("A1:G1")
      .AutoFilter = True
      .AutoFitColumns()
      .Style.Fill.PatternType = ExcelFillStyle.Solid
      .Style.Fill.BackgroundColor.SetColor(Color.DodgerBlue)
      .Style.Font.Color.SetColor(Color.White)
  End With
  
  pck.Save()
  </code></pre>
  
  <p>This results in a file where the columns are all their default widths. There are no formulas in any of the cells, and none are merged. </p>
  
  <p>I then kicked it up and tried using BestFit, but this is also not working.</p>
  
  <pre><code>        For i = 1 To 7
              epWs.Column(i).BestFit = True
          Next
  </code></pre>
  
  <p>(weird how the Columns collection is not zero-based)</p>
  
  <p>Anyway, does anyone have any pointers? Thanks</p>
