嗨，我正在尝试在使用 mysql 查询结果数据填充的表上使用数据表插件。但我收到以下错误。
Uncaught TypeError: Cannot read property 'asSorting' of undefined
请在下面检查我的代码。

在此之后，我在 js 部分调用 js 文件，如下所示。
<script src="js/jquery-1.10.1.js"></script>
<script src="js/jquery.dataTables.js"></script>
$(document).ready(function(event) {
$('#classeslist').dataTable({
"aoColumns": [
null
]
});
});
我试过"aaSorting": [[ 0, "desc" ]]也没有工作。
