title: Showing the data of two rows into one row
body: <p>I have a table with data as </p>
  
  <pre><code>-----------------------------------------------------------------------------
  CUSTOMER    CSAC        CIRCUIT              VALUE       TOWN       POST_CODE
  -----------------------------------------------------------------------------
      RCE |   CSAC125896 |    ICUK809605 |    100 MBPS |  BASILDON |  SS15 5FS
      RCE |   CSAC125896 |    ICUK809605 |    100 MBPS |  BASILDON |  SS15 6AA
  </code></pre>
  
  <p>I want the second post code also to be displayed in the same row if the csac values are same like this </p>
  
  <pre><code>-----------------------------------------------------------------------------
  CUSTOMER  CSAC   CIRCUIT    VALUE        TOWN       POST_CODE   POST_CODE2
  -----------------------------------------------------------------------------
  RCE|CSAC125896 |ICUK809605 |100 MBPS |  BASILDON |  SS15 5FS |  SS15 6AA
  </code></pre>
  
  <p>How can I achieve this result. I have tried using transpose but didn't get the desired result.</p>
