title: Pandas multihirarchical grouping
body: <p>I want to create a multi hirarchical table, although not with a nested dependency. I hope my screenshot, clarifies what i mean by that:</p>
  
  <pre><code>print (df)
    Country   Type data
  0     Ger     VW   oo
  1     Ita  Skoda   kk
  2     Ger  Skoda   oo
  3     Ita     VW   ik
  </code></pre>
  
  <p>On top is a representation of my data, the bottom is the result I hope to achieve.The numbers are the total sums of occurances.</p>
  
  <p>My next step is to visualize it.</p>
  
  <p>Data Frame is called cleaned_df</p>
  
  <p>Thanks a lot for your help!</p>
