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
<!-- 导出 -->
<script type="text/javascript" src="/assets/layui-v2.4.3/table2excel.js"></script>
<script type="text/javascript" src="/assets/layui-v2.4.3/table2excels.js"></script>
<script>
//导出Excel
$("#export_excel").on(‘click‘, function() {
$(".layui-table-box").table2excel({
exclude: ".noExl",
filename: "myFileName" + new Date().toISOString().replace(/[\-\:\.]/g, ""),
fileext: ".xls",
exclude_img: true,
exclude_links: true,
exclude_inputs: true,
sheetName: "student",
excludeFirst:true,
excludeFirst:false
});
});
</script>
