$(function(){
/** 初始化表格*/
$("#departTable").page(Util.tableSetting());
});

var Util = {

tableSetting : function() {
var setting = {

serverSide: true,//打开后台分页
ordering: true,
search: {
smart: false
},
ajax: {
"url": $("#base").val() + "/department/departmentPage.jhtml?columnName=DEPART_ID",
"data": function ( d ) {
//添加额外的参数传给服务器
//d.extra_search = level1;
}
