网上找的库文件，同样做了修改。在导出的时候，有时候数据第一列和最后一列可能是复选框和操作按钮，这个是我们不需要的，加了这个的过滤

前端页面的样子
<div class="layui-row"> <table class="layui-table" lay-data="{url:‘/student/student/oneListJson‘, page:true, id:‘idTable‘, limit: 10}" lay-filter="mtable"> <thead> <tr> <th lay-data="{checkbox:true, fixed: true}"></th> <th lay-data="{templet:‘#studentName‘}">#(i18n.get(‘学生姓名‘))</th> <th lay-data="{field:‘studentEnglishName‘}">#(i18n.get(‘英文姓名‘))</th> <th lay-data="{field:‘birthDateStr‘}">#(i18n.get(‘出生日期‘))</th> <th lay-data="{templet:‘#sex‘}">#(i18n.get(‘性别‘))</th> <th lay-data="{field:‘originalSchool‘}">#(i18n.get(‘就读学校‘))</th> <th lay-data="{field:‘campusName‘}">#(i18n.get(‘所属校区‘))</th> <th lay-data="{field:‘remarks‘}">#(i18n.get(‘备注‘))</th> <th lay-data="{width:60, templet: ‘#status‘}">#(i18n.get(‘状态‘))</th> </tr> </thead> </table> </div> layui的数据表格也可以使用的，简单table也可以使用的 <button type="button" class="layui-btn layui-btn-primary layui-btn-sm" id="export_excel">导出本页数据</button>
使用方式

<script>
//导出Excel
$("#export_excel").on(‘click‘, function() {
