Solution 1

You're creating the table a row at a time, so add the values for each column up as you create it.

You could try with Jquery

XML

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title></title>
</head>
<body>
    <div id="divAllReports"></div>
    <div id="divSum"></div>
    <script src="jquery.js"></script>
    <script type="text/javascript">
        $(document).ready(
            function() {
                var sString = "";
                sString += "<table>";

                sString += "<tr>";
                    sString += "<td>ABC</td>";
                    sString += "<td>300</td>";
                sString += "</tr>";

                sString += "<tr>";
                sString += "<td>PQR</td>";
                sString += "<td>200.75</td>";
                sString += "</tr>";


                sString += "<tr>";
                sString += "<td>xyz</td>";
                sString += "<td>223</td>";
                sString += "</tr>";

                sString += "<tr>";
                sString += "<td>xyz</td>";
                sString += "<td></td>";
                sString += "</tr>";


                sString += "<tr>";
                sString += "<td>xyz</td>";
                sString += "<td>2</td>";
                sString += "</tr>";

                sString += "</table>";
                document.getElementById("divAllReports").innerHTML = sString;


                var sum = 0;

                $('td:nth-child(2)').each(function () {

                    var value = Number($(this).html());
                    if (!isNaN(value)) sum += value;

                });

                $('#divSum').html(sum);
                //
            }
        );

    </script>
</body>
</html>
