我需要在表格的一个列中自动获取序列号.

这是我的示例代码:

<link rel="stylesheet" href="<c:url value='/styles/tablesort.css'/>" />
<script type="text/javascript"

<script type="text/javascript">
    $(function() {
        $("#tabs").tabs();
    });
</script>

<style type="text/css">
table tr td{
text-align:center;
}
</style>


<body>
<div id="tabs" style="width: 880px;">
  <c:if test="${ model != null}">

                <table id="commentsTable" class="tablesorter">
                    <thead>
                        <tr>
                        <th>S.NO<th/>
                        <th><spring:message code="title" /></th>

CSS:

body
{
    counter-reset: Serial;           /* Set the Serial counter to 0 */
}

table
{
    border-collapse: separate;
}

tr td:first-child:before
{
  counter-increment: Serial;      /* Increment the Serial counter */
  content: "Serial is: " counter(Serial); /* Display the counter */
}

将第一列保留为空白并调用javascript方法添加序列号.一个例子如下所示

var addSerialNumber = function () {
    $('table tr').each(function(index) {
        $(this).find('td:nth-child(1)').html(index+1);
    });
};

addSerialNumber();
