Specify Rows or Columns for Excel AutoFit

If you use the Excel AutoFit Method to resize cells to display their contents nicely, remember to specify whether to AutoFit rows or columns in Excel, i.e. use Range().Columns.AutoFit or Range().Rows.AutoFit, not just Range().AutoFit. If you don't specify rows or columns, Excel produces Run-time error '1004': AutoFit method of Range class failed.
