title: How to get pandas crosstab margins value?
body: <p>I got a set of crosstab dataframe which looks like below</p>
  
  <pre><code>Batch     1   2   3   4   All 
  Fruits
  Orange    2   3   4   5    14
  Mango     3   2   1   7    13
  Grape     2   2   2   2     8
  Apple     5   5   8   9    27
  All       13  14  18  27   62
  </code></pre>
  
  <p>The 'All' column and row is generated by the pandas crosstab's margins parameter, so my question is that how can I get the 'All' data by column, which is 13, 14, 18 and 27?</p>
