标准的vue3 elementplus格式,不用export default

<template>
  <div>
    <!-- 查询表单 -->
    <el-form :inline="true" :model="filters" class="demo-form-inline">

</script>

细节：

1. <script setup>：使用 <script setup> 简化了组件结构，不再需要 export default，并且响应式变量和函数自动暴露到模板中。
2. 响应式数据：通过 ref 定义响应式数据，如 mpsList、page、filters 等。
3. 生命周期钩子：使用 onMounted 生命周期钩子在组件挂载时加载数据。
4. 函数：将表单查询、重置、分页等功能以函数形式定义，并通过模板中的事件绑定触发这些函数。
