            var oWB = oXL.Workbooks.Add();
            var oSheet = oWB.ActiveSheet;
            var Lenr = curTbl.rows.length;
            for (i = 0; i < Lenr; i++) {
                var Lenc = curTbl.rows(i).cells.length;
                for (j = 0; j < Lenc; j++) {
                    oSheet.Cells(i + 1, j + 1).value = curTbl.rows(i).cells(j).innerText;
