title: Split multiple values in a column into separate columns
body: <p>My source table looks like this:</p>
  
  <pre><code>A1  12
  A2  13 
  B1  14 
  B2  15 
  B3  16
  </code></pre>
  
  <p>I want it in a format like below: </p>
  
  <pre><code>     1   2   3
  A   12  13
  B   14  15  16
  </code></pre>
  
  <p>Since there is large amount of data, it can't be done manually.  </p>
  
  <p>Please let me know how to do this?</p>
