title: Split multi valued cells in more than one column into rows (Open Refine)
body: <p>I have been cleaning a table on Open Refine. I now have it like this:</p>
  
  <pre><code>REF                 Handle      Size        Price
  2002, 2003          t-shirt1    M, L        23
  3001, 3002, 3003    t-shirt2    S, M, L     24
  </code></pre>
  
  <p>I need to split those multivalued cells in REF and Size so that I get:</p>
  
  <pre><code>REF                 Handle      Size        Price
  2002                t-shirt1    M           23
  2003                t-shirt1    L           23  
  3001                t-shirt2    S           24  
  3002                t-shirt2    M           24
  3003                t-shirt2    L           24
  </code></pre>
  
  <p>Is it possible to do this in Open Refine? The "Split multi-valued cells..." command only takes care of one column.
  Thank you,
