      var currentDate = new Date()
      var day = currentDate.getDate()
      var month = currentDate.getMonth() + 1
      var year = currentDate.getFullYear()
  
      var d = day + "-" + month + "-" + year;
      $('#detailTable').DataTable({
          dom: 'Bfrtip',
          buttons: [{
              extend: 'excelHtml5',
              title: d + ' Purchase Orders'
          }, {
              extend: 'csvHtml5',
              title: d + ' Purchase Orders'
          }, {
              extend: 'pdfHtml5',
              title: d + ' Purchase Orders',
              orientation: 'landscape',
              pageSize: 'LEGAL',
              exportOptions: {
                  columns: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
