今天遇到一个Datatables常见的问题，搞了好久没弄好，查看baidu也没有成果，在google上查到了原因。

问题：
DataTables warning: Requested unknown parameter '3' from the data source for row 0
?
JS:
function initializeEvents() {$('.datatable').dataTable({"sDom": "<'row-fluid'<'span6'l><'span6'f>r>t<'row-fluid'<'span12'i><'span12 center'p>>","bServerSide" : true,"sAjaxSource" : "/uploadDemo/admin/photo/list.spring", "sServerMethod" : "POST" , "bProcessing" : false, "bPaginate": true,"bLengthChange" : true,"iDisplayLength" : 10,"fnAdjustColumnSizing" : false,"bStateSave": false,"bSort":false,"bFilter":false,"aoColumnDefs" : makeCollumnDef(),"aoColumns" : makeCollomns(),"sPaginationType": "bootstrap","oLanguage": {"sLengthMenu": "_MENU_ records per page"}} );}function makeCollumnDef() {return [ { "fnRender" : function (oObj, sVal) { return oObj.aData.id; }, "bVisible" : true , "aTargets" : [ 0 ] }, { "fnRender" : function (oObj, sVal) { return oObj.aData.name; }, "bVisible" : true , "aTargets" : [ 1 ] }, { "fnRender" : function (oObj, sVal) { return "<img src='/uploadDemo/" +oObj.aData.path +"' width=50px height=40px />"; }, "bVisible" : true , "aTargets" : [ 2 ] }, { "fnRender" : function (oObj, sVal) { return createAction(oObj.aData.id); }, "bVisible" : true , "aTargets" : [ 3 ] }]; }function makeCollomns(){return [{ "mDataProp" : "id", "sHeight":"15px"}, { "mDataProp" : "name"}, { "mDataProp" : "path"}}];}function createAction(id) {var inhtml = '<a href="/uploadDemo/admin/photo/view.spring?id=' + id + '">';inhtml += '<i href="/uploadDemo/admin/photo/preUpdate.spring?id=' + id + '">';inhtml += '<i href="/uploadDemo/admin/photo/delete.spring?id=' + id + '">';inhtml += '<i name="code">public class PhotoBean { private int id; private String name; private String path; private String checked;?
function makeCollomns(){return [{ "mDataProp" : "id", "sHeight":"15px"}, { "mDataProp" : "name"}, { "mDataProp" : "path"}, { "mDataProp" : "checked"}];?
我添加了一个checked的字符串，问题解决。
