导出效果：

<table id="table_1" lay-filter="table_1"></table>//table表格初始化
table.render({elem: '#table_1',id: 'table1',url: '/xxx/list',where:{month:formattedTime,},page: true,method: 'get',cols: cols,skin: 'line',toolbar: '#role-toolbar',defaultToolbar: [{layEvent: 'refresh',icon: 'layui-icon-refresh',}, 'filter', 'print', 'exports'],parseData: function (res) {return {"code" : 0,"msg": "","count": res.count,"data":res.data,}},done:function(res,curr,count){if(res.code != 0){layer.msg("数据返回有误！")return false;}exportData = res.data;var selLength=res.count;//导出按钮初始化dropdown.render({elem: '#downMenu',align: "left",data: [{title: '导出选中',templet: '<div class="export-select">{{d.title}}</div>',id: 100}, {title: '导出所有',templet: '<div class="export-all">{{d.title}}</div>',id: 101}],ready: function () {//获取table实例var checkStatus = table.checkStatus('table1');$(".export-select").html("导出选中 (已选" + checkStatus.data.length + "条)");$(".export-all").html("导出所有 (共" + selLength + "条)");if (checkStatus.data.length == 0) {$(".export-select").addClass("export-selectNo");} else {$(".export-select").removeClass("export-selectNo");}},click: function (obj) {var param={};//导出全选参数//选中导出if (obj.id == 100) {var checkTab = table.checkStatus('table1');checkTebData = checkTab.data;table.exportFile('table1', checkTebData, 'xlsx', '我的xx' + getCurDate('-'));}// 全部到处（本页全部数据，接口全部导出）else {//本页导出checkTebData = exportData;table.exportFile('table1', checkTebData, 'xlsx', '我的xx' + getCurDate('-'));//接口全部导出param={xx:1yy:2}window.listExport(param)}}});},
