datatables如何把列设置成hidden隐藏域？

官网：https://datatables.net/reference/option/
设置： visible: false
如下：

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">

    <script src="../../js/jquery-1.9.1.min.js"></script>
    <script src="../../js/layer/layer.js"></script> 
    <script src="../../js/public.js"></script>

    <script src="../../js/datatables/jquery.dataTables.min.js"></script>

</head>

<body>

<div align="center" style="width: 99%;">
    <table id="dataGrid" align="center"  border="1" style="width: 100%;">
        <thead>
        <tr>
            <th style="display: none">patrolRecordId</th>
