配合element-ui的分页和表格控件实现本地数据分页效果

也不多说了直接上代码

<template>
  <div>
    <div>表格本地分页</div>
    <el-table :data="tableData" border>
      <el-table-column prop="id" label="序号"></el-table-column>
      <el-table-column prop="name" label="名称"></el-table-column>
      <el-table-column prop="age" label="年龄"></el-table-column>
    </el-table>
    <el-pagination @size-change="handleSizeChange" @current-change="handleCurrentChange" :current-page="index" :page-sizes="[2, 4, 6, 8,10]" :page-size="size" layout="total, sizes, prev, pager, next, jumper" :total="tableCopyTableList.length">
    </el-pagination>
  </div>
</template>
