vue+element的表格分页和搜索功能

        最近在做后台系统,要求就是要做一个table表格,需要有分页和搜索的功能。框架是主流框架Vue,组件库选用的是elementui。

以下就是简单的,还没有添加任何操作的demo

<template>
  <div>
    <el-input v-model="tableDataName" placeholder="请输入姓名" style="width:240px"></el-input>
    <el-button type="primary" @click="doFilter">搜索</el-button>
    <el-table
      :data="tableDataEnd"
      border
      style="width: 100%">.
      <el-table-column
        prop="date"
        label="日期"
        width="180">
      </el-table-column>
      <el-table-column
        prop="name"
        label="姓名"
        width="180">
      </el-table-column>
      <el-table-column
        prop="address"
        label="地址">
      </el-table-column>
    </el-table>
    <el-pagination
      @size-change="handleSizeChange"
      @current-change="handleCurrentChange"
      :current-page="currentPage"
      :page-sizes="[1, 2, 3, 4]"
      :page-size="pageSize"
      layout="total, sizes, prev, pager, next, jumper"
      :total="totalItems">
    </el-pagination>
  </div>
</template>
<script>
