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"/>"  }]
