element 分页如何使用

<template>
  <el-table :data="tableData.slice((page - 1) * limit, page * limit)" style="width: 100%">
    <el-table-column prop="date" label="Date" width="180" />
    <el-table-column prop="name" label="Name" width="180" />
    <el-table-column prop="address" label="Address" />
  </el-table>
  <!-- 分页 -->
  <el-pagination
    :current-page="page"
    small
    background
    layout="prev, pager, next"
    :total="total"
    class="mt-4"
    :page-size="limit"
    @size-change="handleSizeChange"
    @current-change="handleCurrentChange"
  />
</template>

<script setup>
// 分页
const limit = ref(3); // 每页数据
const page = ref(1); // 默认页数
const total = ref(0); // 总的数据
const tableData = [
  {
    date: '2016-05-03',
    name: 'Tom',
    address: 'No. 189, Grove St, Los Angeles',
  },
  {
    date: '2016-05-02',
    name: 'Tom',
    address: 'No. 189, Grove St, Los Angeles',
  },
  {
    date: '2016-05-04',
    name: 'Tom',
    address: 'No. 189, Grove St, Los Angeles',
  },
  {
    date: '2016-05-01',
    name: 'Tom',
    address: 'No. 189, Grove St, Los Angeles',
  },
  {
    date: '2016-05-01',
    name: 'Tom',
    address: 'No. 189, Grove St, Los Angeles',
  },
  {
    date: '2016-05-01',
    name: 'Tom',
    address: 'No. 189, Grove St, Los Angeles',
  },
  {
    date: '2016-05-01',
    name: 'Tom',
    address: 'No. 189, Grove St, Los Angeles',
  },
];
total.value = tableData.length;
// 分页
const handleSizeChange = (val) => {
  limit.value = val;
};
const handleCurrentChange = (val) => {
  page.value = val;
};
