<template>
  <div id="app">
    <el-table
    :data="tableData.slice((currentPage-1)*size,currentPage*size)"
    border
    style="width: 100%">

  </el-table>
  <div class="block" style="margin-left:30%">
    <!-- <span class="demonstration">完整功能</span> -->
    <el-pagination
      @size-change="handleSizeChange"
      @current-change="handleCurrentChange"
      :current-page="currentPage"
      :page-sizes="[5, 10, 15, 20]"
      :page-size="size"
      layout="total, sizes, prev, pager, next, jumper"
      :total="tableData.length">
    </el-pagination>
  </div>
  </div>
