用 vue3 + element plus UI 帮我写一个列表页面。列表满足的要求 1 有搜索功能可以根据输入的关键字 和 状态下拉选项 进行列表的查询。2 有分页功能每页显示 102050 条数据。3 并且列表有一个操作列操作列有两个按钮一个是编辑一个是删除。4 列表的数据是从后端获取的后端接口是 apilist请求方式是 get请求参数是 page 和 pageSize返回的数据格式是 c

以下是一个基本的列表页面，包括搜索、分页、操作列、树形结构、多选删除等功能：

<template>
  <div>
    <el-form :inline="true">
      <el-form-item label="关键字">
        <el-input v-model="keyword" placeholder="请输入关键字"></el-input>
      </el-form-item>
      <el-form-item label="状态">
        <el-select v-model="status" placeholder="请选择状态">
          <el-option label="全部" value=""></el-option>
          <el-option label="状态1" value="1"></el-option>
          <el-option label="状态2" value="2"></el-option>
        </el-select>
      </el-form-item>
      <el-form-item>
        <el-button type="primary" @click="search">查询</el-button>
      </el-form-item>
    </el-form>
    <el-table :data="tableData" style="width: 100%">
      <el-table-column type="selection"></el-table-column>
      <el-table-column prop="name" label="名称"></el-table-column>

      <el-table-column label="操作">
        <template #default="{ row }">

          <el-button type="danger" size="small" @click="del(row)">删除</el-button>
        </template>
      </el-table-column>
      <el-table-column label="子节点">
        <template #default="{ row }">
          <el-button type="primary" size="small" v-if="row.children && !row.childrenLoaded" @click="loadChildren(row)">加载子节点</el-button>
          <el-tree
            v-if="row.children"
            :data="row.children"

    <el-pagination
      v-if="total > 0"
      :total="total"
      :page-size="pageSize"
      :current-page.sync="currentPage"
      @current-change="getPageData"
    ></el-pagination>
    <el-button type="danger" @click="delSelected" style="margin-top: 10px">批量删除</el-button>
  </div>
</template>
