Answer 1

js DOM进行 啊document.getElementById("设置个tableID").rows[i].cells[j]得到各个单元格，累加就可以了

Answer 2

    <script type="text/javascript">
        $(document).ready(function () {
            $("#tbid tr:last td:eq(0)").html("合计：" + ($("#tbid tr").length - 2));
            var val1 = 0;
            var val2 = 0;
            $("#tbid tr:gt(0)").not(":last").each(function () {
                val1 += parseInt($(this).find("td:eq(1)").html());
                val2 += parseInt($(this).find("td:eq(2)").html());
            })
            $("#tbid tr:last td:eq(1)").html(val1);
            $("#tbid tr:last td:eq(2)").html(val2);
        })
    </script>    <div>
        <table border="1" cellpadding="5" cellspacing="0" style="border-collapse: collapse; width: 400px;" id="tbid">
            <tr align="center" style="height: 25px;">
                <th style="width: 50px; line-height: 120%;">序号</th>
                <th style="width: 150px; line-height: 120%;">样文</th>
                <th style="width: 200px; line-height: 120%;">录入列</th>
            </tr>
            <tr align="center" style="height: 25px;">
                <td style="width: 50px; line-height: 120%;">12</td>
