DataTable插件报错：Uncaught TypeError: Cannot read property 'style' of undefined

DataTable插件报错：Uncaught TypeError: Cannot read property 'style' of undefined

原因：table 中定义的列和aoColumns数据表的项数量对不上：比如下面：

<table class="table dataTable ">
    <thead>
    <tr>
        <th>列1</th>
        <th>列2</th>
    </tr>
    </thead>
    <tbody>
    </tbody>
</table>

 

"aoColumns": [
    {
        "mDataProp": "uuid",
        "sDefaultContent": "",
        "fnRender": function (obj) {
var sReturn = "<input type='checkbox' name='check' value='" + obj.aData.uuid + "' />";
return sReturn;
        }
    },
    {
        "mDataProp": "warehouseName",
        "sDefaultContent": "",
        "sTitle": "<aebiz:showTitle titleId="productsuresalestock.m.warehouseName"/>"
    },
    {
        "mDataProp": "warehouseNo",
        "sDefaultContent": "",
        "sTitle": "<aebiz:showTitle titleId="productsuresalestock.m.warehouseNo"/>"
    }]
