title: Excel button issue in Safari using datatable
body: <p>I got problem about my button, which allows to export data to .xlsx file. It works good for Edge, Mozilla and Chrome, but if I try <strong>Safari on iphone or Macbook</strong> it seems that button is just missing and invisible.</p>
  
  <p>I really need help with this, because can't find a proper solution. Data export should fully work on Safari, Mozilla, Edge, Chrome.</p>
  
  <p><strong>Maybe someone faced similar problem?</strong>
  My code:</p>
  
  <pre><code>$(document).ready(function() {
  var table = $('#tableOrders').DataTable( {
      "bFilter" : true,               
      "bLengthChange": true,
      "paging":   true,
      "ordering": true,
      "order": [[ @if ($user-&gt;role=='super_admin') 7 @else 6 @endif, "desc" ]],
      "info":true,
      dom: 'lBfrtip',
      lengthMenu: [
          [ 10, 25, 50, -1 ],
          [ '10', '25', '50', 'Show all' ]
      ],
      buttons: [
          {
              extend: 'copyHtml5',
              text: '&lt;b&gt;Copy all&lt;/b&gt;',
              exportOptions: {
                  columns: [@if($user-&gt;role=='super_admin') 0, 1, 2, 3, 4, 5, 6 @else 0, 1, 2, 3, 4 @endif]
              }
          },
          {
              extend: 'excelHtml5',
              text: 'Export all to &lt;b&gt;Excel&lt;/b&gt;',
              exportOptions: {
                  columns: [@if($user-&gt;role=='super_admin') 0, 1, 2, 3, 4, 5, 6 @else 0, 1, 2, 3, 4 @endif]
              }
          },
      ]
  } );
  </code></pre>
