title: Pandas Pivot_Table - Add Grand Total and change Order
body: <p>I have the following sample code:</p>
  
  <pre><code>import pandas as pd 
  import numpy as np
  d = {'Fruit': ['Apples', 'Oranges', 'Apples', 'Kiwi', 'Kiwi'], 'Amount': 
       [10, 15, 65, 5, 13]}
  
  df = pd.DataFrame(data=d)
  
  table = pd.pivot_table(df, index='Fruit', aggfunc= np.sum)
  </code></pre>
  
  <p>The table results appear like this:</p>
  
  <pre><code>Fruit   Amount
  Apples  75
  Kiwi    18
  Oranges 15
  </code></pre>
  
  <p>How do you add a grand total to the bottom?  Also, I'd like to choose the order, example:  </p>
  
  <pre><code>Fruit      Amount
  Oranges    15
  Apples     75
  Kiwi       15
  Total      105
  </code></pre>
  
  <p>How do I go about doing this?
  Thanks!</p>
