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。
