jquery动态合并表格行

利用<td rowspan = "num"/>;原理来实现，其中num为要合并的行数。

<!DOCTYPE html>
<html>
<head lang="en">
    <meta charset="UTF-8">
    <title></title>
    <style>
        td{
            border:1px solid red;
        }
    </style>
</head>
<body>
<table class="table mbn tc-med-1 tc-bold-last tc-fs13-last" id="table1">
    <thead>
    <tr>
        <th>品牌</th>
        <th>车型</th>
        <th>性别</th>
        <th>配额数</th>
        <th>完成数</th>
    </tr>
    </thead>
    <tbody>
    <tr>
        <td>宝马</td>
        <td>3系</td>
        <td>男</td>
        <td>200</td>
        <td>100</td>
    </tr>
    <tr>
        <td>宝马</td>
        <td>3系</td>

        <td>100</td>
        <td>57</td>
    </tr>
    <tr>
        <td>宝马</td>
        <td>5系</td>
        <td>男</td>
        <td>100</td>
        <td>68</td>
    </tr>
    <tr>

    </tr>
    <tr>
        <td >宝马</td>

<script>
    jQuery.fn.rowspan = function(colIdx) { //封装的一个JQuery小插件
        return this.each(function(){
            var that;
            $('tr', this).each(function(row) {
                $('td:eq('+colIdx+')', this).filter(':visible').each(function(col) {
                    if (that!=null && $(this).html() == $(that).html()) {
                        rowspan = $(that).attr("rowSpan");
                        if (rowspan == undefined) {
                            $(that).attr("rowSpan",1);
                            rowspan = $(that).attr("rowSpan"); }
                        rowspan = Number(rowspan)+1;
                        $(that).attr("rowSpan",rowspan);
                        $(this).hide();
                    } else {
                        that = this;
                    }
                });
            });
        });
    }
    $(function() {
        $("#table1").rowspan(0);//传入的参数是对应的列数从0开始
        $("#table1").rowspan(1);
        $("#table1").rowspan(2);
        $("#table1").rowspan(3);
    });
</script>

其它几种方法：
