title: Show records per page drop down along with export button on datatables
body: <p>Unable to show records per page drop down after displaying the export buttons.
  I want to display both of them on my table. Here is my code:</p>
  
  <pre><code>$(document).ready(function() {
      $('#dataTables-example').DataTable({
          pageLength: 5,
          dom: 'Bfrtip',
          buttons: ['csv', 'excel', 'pdf', 'print'],
          responsive: true
      });
      $('.datetext').datepicker({
          format: "yyyy-mm-dd"
      });
  });
  </code></pre>
  
  <p>Records per page drop down displayed if I remove the buttons on the tables, But I want to display both of them. How to display both of them?</p>
