I need to add customized title for excel file exported from Datatable. Tried this from a stackoverflow answer but it applies to whole sheet.

$("#datatable").DataTable({
          dom: "lBfrtip",
          buttons: [
            {
              extend: "excelHtml5",
              title: "Audit Trail Report",
              messageTop: `From ${this.start_date} To ${this.end_date}`,
              customize: function (xlsx) {
                var sheet = xlsx.xl["styles.xml"];
                var tagName = sheet.getElementsByTagName("sz");
                for (let i = 0; i < tagName.length; i++) {
                  tagName[i].setAttribute("val", "22");
                }
              },
            },
            {
              extend: "pdf",
              title: "Audit Trail Report",
              messageTop: `From ${this.start_date} To ${this.end_date}`,
            },
          ],
          searching: false,
        })
