title: DataTables fixed column transparent with Bootstrap 4 striped table
body: <p>In DataTables example <a href="https://datatables.net/extensions/fixedcolumns/examples/styling/bootstrap4.html" rel="nofollow noreferrer">here</a>, when scroll the table to left, fixed cell is transparent on dark rows.</p>
  
  <p>Is this a bug related BS4 or DataTables. If so, is there a workaround to correct it?</p>
