We don't support button extensions from datatable in our docs. But if you want to do this you can use this code and it will be work.

You have to have extensions like that.

  <script type="text/javascript" src="../js/addons/datatables.min.js"></script>
  <script src="https://cdn.datatables.net/buttons/1.5.6/js/dataTables.buttons.min.js"></script>
  <script src="https://cdn.datatables.net/buttons/1.5.6/js/buttons.flash.min.js"></script>
  <script src="https://cdnjs.cloudflare.com/ajax/libs/jszip/3.1.3/jszip.min.js"></script>
  <script src="https://cdnjs.cloudflare.com/ajax/libs/pdfmake/0.1.53/pdfmake.min.js"></script>
  <script src="https://cdnjs.cloudflare.com/ajax/libs/pdfmake/0.1.53/vfs_fonts.js"></script>
  <script src="https://cdn.datatables.net/buttons/1.5.6/js/buttons.html5.min.js"></script>
  <script src="https://cdn.datatables.net/buttons/1.5.6/js/buttons.print.min.js"></script>
  <script type="text/javascript" src="../js/addons/mdb-editor.js"></script>

and initiate functions like this ( there is a exmalpe with data and columns for JSON file, you don't have to do this) :

$(document).ready(function () {
  $('#example').DataTable({
    data: myJasonData.responseJSON.data,
    columns: myJasonData.responseJSON.columns,
    dom: 'Bfrtip',
    buttons: [
      'copy', 'csv', 'excel', 'pdf', 'print'
    ]
  });

  $('#example').mdbEditor({
    modalEditor: true
  });
});

$('.dataTables_length').addClass('bs-select');

If you will do that there will show buttons like that.
