DataTables warning: Requested unknown parameter '0' from the data source for row '0'

问题：DataTables warning: Requested unknown parameter ‘0‘ from the data source for row ‘0‘

 

代码：

<script type="text/javascript">

var data = [
    {"Name":"UpdateBootProfile","Result":"PASS","ExecutionTime":"00:00:00","Measurement":[]},
    {"Name":"NRB Boot","Result":"PASS","ExecutionTime":"00:00:50.5000000","Measurement":[{"TestName":"TOTAL_TURN_ON_TIME","Result":"PASS","Value":"50.5","LowerLimit":"NaN","UpperLimit":"NaN","ComparisonType":"nctLOG","Units":"SECONDS"}]},
    {"Name":"NvMgrCommit","Result":"PASS","ExecutionTime":"00:00:00","Measurement":[]},
    {"Name":"SyncNvToEFS","Result":"PASS","ExecutionTime":"00:00:01.2500000","Measurement":[]}
];

$(function() {
        var testsTable = $(‘#tests‘).dataTable({
                bJQueryUI: true,
                aaData: data,
                aoColumns: [
                        { mData: ‘Name‘ },
                        { mData: ‘Result‘ },
                        { mData: ‘ExecutionTime‘ },
　　　　　　　　　　　　{ mData: ‘localtion‘ }

] }); }); </script>

报错原因： 这个location字段，有数据的时候出现，没有数据的时候，就成这个样子了

   aoColumns: [
                        { mData: ‘Name‘ },
                        { mData: ‘Result‘ },
                        { mData: ‘ExecutionTime‘ }
导致页面错误。

改正的方法是：
1.$(‘#example‘).dataTable( {

  "columns": [

    null,

    null,

    null,

    {

      "data": "office", // can be null or undefined

      "defaultContent": ""

    }

  ]

} );  加上【"defaultContent": ""】

2. 用都是数组的形式

var data = [
    ["UpdateBootProfile","PASS","00:00:00",[]] ,
    ["NRB Boot","PASS","00:00:50.5000000",[{"TestName":"TOTAL_TURN_ON_TIME","Result":"PASS","Value":"50.5","LowerLimit":"NaN","UpperLimit":"NaN","ComparisonType":"nctLOG","Units":"SECONDS"}]] ,
    ["NvMgrCommit","PASS","00:00:00",[]] ,
    ["SyncNvToEFS","PASS","00:00:01.2500000",[]]
];
