我有一个用于在管理后端中显示表格的类；但是桌子从右边溢出了，我不确定为什么。我的数据没有填满单元格，也没有任何代码设置宽度。我选择了另一个效果很好的插件，并对其进行了修改以进行一些改进。显然，我所做的某件事导致了问题，但我不知道该怎么办。
这是我的课程...

在调用它时，我也没有做任何时髦的事情...
function GJ_signatures()
{
//Prepare Table of elements
$GJ_Signature_Table = new GJ_Signature_Table();
$GJ_Signature_Table->prepare_items();
//Table of elements
// $GJ_Signature_Table->display();
?>
<form id="signatures" method="get">
<!-- For plugins, we also need to ensure that the form posts back to our current page -->
<input type="hidden" name="page" value="<?php echo $_REQUEST['page'] ?>" />
<!-- Now we can render the completed list table -->
<?php $GJ_Signature_Table->display() ?>
</form>
<?php
}
当我错过简单的事情时，我讨厌它...需要用<form>包围<div>
<div class="wrap"><form.....></form></div>
