title: Trouble writing pivot table to excel file
body: <p>I am using pandas/openpyxl to process an excel file and then create a pivot table to add to a new worksheet in the current workbook. When I execute my code, the new sheet gets created but the pivot table does not get added to the sheet.</p>
  
  <p>Here is my code:</p>
  
  <pre><code>worksheet2 = workbook.create_sheet()
  worksheet2.title = 'Sheet1'
  workbook.save(filename)
  
  excel = pd.ExcelFile(filename)
  df = excel.parse(sheetname=0)
  df1 = df[['Product Description', 'Supervisor']]
  
  table1 = pd.pivot_table(df1, index = ['Supervisor'],
                             columns = ['Product Description'],
                            values = ['Product Description'],
                             aggfunc = [lambda x: len(x)], fill_value = 0)
  
  
  
  print table1
  
  writer = pd.ExcelWriter(filename)
  table1.to_excel(writer, 'Sheet1')
  writer.save()
  workbook.save(filename)
  </code></pre>
  
  <p>When I print out my table I get this:</p>

  <p>I would like the pivot table to look like this: (if my pivot table code won't make it look like this could someone help me make it look like that? I'm not sure how to add the grand total column. It has something to do with the aggfunc portion of the pivot table right?)</p>
