我正在尝试使用jQuery将HTML插入表元素中。我一直在搞乱选择器的变化（下面）而没有运气。有人能帮助我吗？
我的选择器：
$j('#ctl00_body_gridData_dom').children('table:first').append("<thead><tr><td colspan='6'> </td><td align='center' colspan='7'>EM SPECS</td><td align='center' colspan='7'>FISH</td><td colspan='11'> </td></tr></thead>");
这就是我想要做的......
我想插入此内容：
<thead>
<tr>
<td colspan="6">
</td>
<td align="center" colspan="7">
EM SPECS
</td>
<td align="center" colspan="7">
FISH
</td>
<td colspan="11">
</td>
</tr>
</thead>
下面的示例是我希望最终结果看起来像......
所以它看起来像这样： Jquery事件池
<table id="ctl00_body_gridData" style="width: 2000px; -moz-user-select: none;" border="1" cellpadding="0" cellspacing="0">
<tbody>
<tr>
<td id="ctl00_body_gridData_dom" class="GridData" style="vertical-align: top; height: 245px;" valign="top">

将您选择的内容更改为：
