            var table = document.getElementById(tableID);

            var rowCount = table.rows.length;
            var row = table.insertRow(rowCount);

            var cell1 = row.insertCell(0);
            var element1 = document.createElement("input");
            element1.type = "checkbox";
            element1.name="chkbox[]";
            cell1.appendChild(element1);

            var cell2 = row.insertCell(1);
            var element2 = document.createElement("input");
            element2.type = "text";
            element2.name="txtbox[]";
            cell2.appendChild(element2);
            //cell2.innerHTML = rowCount + 1;

            var cell3 = row.insertCell(2);
            var element3 = document.createElement("textarea");
            element3.type = "textarea";
            element3.name = "textarea[]";
            cell3.appendChild(element3);


        }

        function deleteRow(tableID) {
            try {
            var table = document.getElementById(tableID);
            var rowCount = table.rows.length;

            for(var i=0; i<rowCount; i++) {
                var row = table.rows[i];
                var chkbox = row.cells[0].childNodes[0];
                if(null != chkbox && true == chkbox.checked) {
                    table.deleteRow(i);
                    rowCount--;
