今天做一个jquery功能的时候遇到一个问题，好像是for循环出现了问题，我解决不了，大家帮忙看看哦，先谢谢你们！ 代码如下：
<table width="795" class="admin_table" cellpadding="0" cellspacing="0">
                             <tr>
                                 <td class="admin_td1" style="border-top:1px solid #ccc">XCC001</td>
                                    <td class="admin_td1" style="border-top:1px solid #ccc">田克群</td>
                                    <td style="border-top:1px solid #ccc">
                                     <span class="ad_sp_1">已开通</span>
                                        <span class="ad_sp_2">点击取消</span>
                                    </td>
                                </tr>
                                <tr>
                                 <td class="admin_td1">XCC002</td>
                                    <td class="admin_td1">郭德华</td>
                                    <td>
                                     <span class="ad_sp_1">已开通</span>
                                        <span class="ad_sp_2">点击取消</span>
                                &nbs
