dataTable中时间类型数据格式化

var table=$('.table-sort').dataTable({
            "Processing": false, // 是否显示取数据时的那个等待提示
            "bServerSide": true,//这个用来指明是通过服务端来取数据
            "bPaginate": true,  //是否显示分页
            "sAjaxSource": "${cxtPath}/employee/ListPageByName",//这个是请求的地址
            "fnServerData": retrieveData, // 获取数据的处理函数
            "columnDefs": [{
                    "defaultContent": "",
