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,
