DataTables warning : Requested unknown parameter '1' from the data source for row 0错误

昨天在做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 '1' 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",



	"sAjaxSource" : "${basePath}/logInfo/getLogInfo",



	"aoColumns" : [ {

		"bVisible" : true,

		"mData" : "providerName",

		"aTargets" : [ 0 ]

	}, ],

	"aoColumnDefs" : [ {

		sDefaultContent : '',

		aTargets : [ '_all' ]

	} ],



	"oLanguage" : {

		"sProcessing" : "正在加载中......",
