title: Datatables warning (table id = 'ideas'): cannot reinitialise data table
body: <p>I am using data tables and am adding options to the JS code, the changes work but I keep on getting a popup warning. How can I stop the warning? </p>
  
  <pre class="lang-js prettyprint-override"><code>$(document).ready(function() {
      $('#ideas').dataTable( {
          "aLengthMenu": [[5, 10, 15, -1], [5, 10, 50, "All"]]
      });
  });
