title: dataTables read columns from ajaxsource
body: <p>Can <a href="http://datatables.net" rel="nofollow">DataTables</a> read columns (names) list from its ajaxSource?</p>
  
  <p>I mean that I define columns in my <code>PHP</code> file and pass them with data, then <code>dataTables</code> parses them and create the table (full dynamically)</p>
  
  <p>Thanks. </p>
