你可以使用layui的table组件和form组件来实现动态新增带下拉框的行。
首先,你需要在HTML中创建一个空的table,并设置好表头,如下所示:
```html
<table id="demo" lay-filter="test"></table>
```
然后,在JavaScript中初始化table组件,并定义好表格列的数据和渲染方式,如下所示:
```javascript
layui.use(['table', 'form'], function(){
var table = layui.table;
var form = layui.form;
//定义表格列的数据
var cols = [[
{field: 'name', title: '姓名'},
{field: 'age', title: '年龄'},
{field: 'gender', title: '性别', templet: '#genderTpl'}
]];
//渲染表格
table.render({
elem: '#demo',
cols: cols,
data: []
});
//定义性别下拉框的模板
var genderTpl = '<select name="gender"><option value="男">男</option><option value="女">女</option></select>';
//监听表单的提交事件,添加新的数据行
form.on('submit(add)', function(data){
var newData = {name: data.field.name, age: data.field.age, gender: data.field.gender};
var oldData = table.cache.demo;
oldData.push(newData);
table.reload('demo', {data: oldData});
return false;
});
//将性别下拉框模板添加到HTML中
$('body').append('<script type="text/html" id="genderTpl">'+ genderTpl +'</script>');
});
```
在上面的代码中,我们首先定义了表格列的数据和渲染方式,然后初始化了table组件,并将空的表格渲染出来。然后,我们定义了一个性别下拉框的模板,并将其添加到HTML中。最后,我们监听了表单的提交事件,在提交表单时,将新的数据添加到原有数据中,并重新加载表格。
注意,上面的代码中,我们使用了form组件来监听表单的提交事件。因此,在HTML中,你需要创建一个表单,并为其添加一个监听事件,如下所示:
```html
<form class="layui-form" lay-filter="addForm">
<div class="layui-form-item">
<label class="layui-form-label">姓名</label>
<div class="layui-input-inline">
<input type="text" name="name" lay-verify="required" placeholder="请输入姓名" autocomplete="off" class="layui-input">

</div>
<div class="layui-form-item">
<label class="layui-form-label">年龄</label>
<div class="layui-input-inline">
<input type="text" name="age" lay-verify="required|number" placeholder="请输入年龄" autocomplete="off" class="layui-input">

```
上面的代码中,我们为表单添加了一个监听事件,当表单被提交时,会触发JavaScript中的form.on('submit(add)')方法,从而实现动态新增带下拉框的行。
