**结构：**
<template>
<Paging
   :current-page="page.currentPage"
   :page-size="page.pageSize"
   :background="page.background"
   :layout="page.layout"
   :total="page.total"
   :limit="page.limit"
   @handleSizeChange="page.handleSizeChange"
   @handleCurrentChange="page.handleCurrentChange"
 ></Paging>
</template>
**js:**
<script setup>
import Paging from "@/components/paging";//引入分页组件
const page = reactive({
  layout:'prev, pager, next, jumper',
  currentPage:1,
  limit:10,
  total:300,
  handleSizeChange:(val)=>{
    page.pageSize = val
  },
  handleCurrentChange:(val)=>{
   page.currentPage = val
  }
})
</script>
