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

在做datatables的项目,从后台取得数据后，返回给datatables界面时会报下面的错误:

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

加上下面的设置就可以了，至于原理还不是很清楚。

"aoColumnDefs": [
{
 sDefaultContent: '',
 aTargets: [ '_all' ]
  }
],

var oTable = $("#example").dataTable({
    "bDeferRender" : true,
    "bFilter" : false,
    "bDestroy" : true,
    "bProcessing" : true,
    "bSort" : true,
    "bStateSave" : false,
    // 异步处理必须 否则数据发送不到后来
    "bServerSide" : true,
    "sServerMethod" : "POST",

    "aoColumns" : [ {
