title: Multiple column categories in MS Excel pivot table
body: <p>Is it possible to design a pivot table in such a way that I have multiple column categories? Please see examples below:</p>
  
  <pre><code>|Group  |      Category 1     |      Category 2     |
  |       | good |  bad | total | good |  bad | total |
  |---------------------------------------------------|
  |Group 1|  40% |  60% |  100% |  60% |  40% |  100% |
  |Group 2|  30% |  70% |  100% |  20% |  80% |  100% |
  ...
  </code></pre>
  
  <p>I can get the Category 1 part or the Category 2 part, but not both. If you put both as my column input, I get the combined version (i.e. good/good, good/bad, bad/good, and bad/bad).</p>
  
  <p>Thanks</p>
