  <p>I'd like output as follows:</p>
  
  <pre><code>Account Contact1    Contact2    Contact3    Contact4
  
  1   324324324   674323234       
  2   833343432   433243443       
  3   787655455           
  4   754327545   455435435       
  5   543544355   432455553   432433242   432432432
  </code></pre>
  
  <p>The problem is also that I have an unfixed amount of Accounts &amp; unfixed amount of Contacts</p>
