总体配置其实和vue2 的 el-pagination差不多，不过将页码和页数的调用事件回调了回来，我们这里既可以单独使用这个分页组件，也可以和我前面写得 通用表格组件 一起使用，通用表格组件里内置了本分页组件。（注： 写时候有点急，所以没写啥注释，要用本代码但是不怎么理解的，可以下面评论，我基本上会看的哦~）

// 本页条数改变
emit('pagination', { page: currentPage, limit: val })
// 页数改变
emit('pagination', { page: val, limit: pageSize })

// 父组件调用方式
<template>
<Pagination v-show="pageInfo.totalCount > 0"
  :total="pageInfo.totalCount"
  :page="pageInfo.pageIndex"
  :limit="pageInfo.pageSize"
  :pageSizes="pageInfo.pageArr"
      @pagination="getList" />
</template>
<script lang="ts">
const getList = (pages: any) => {
    let { page, limit } = pages
    if (!isNumber(page)) {
      page = page.value
    }
    if (!isNumber(limit)) {
      limit = limit.value
    }
    const pageInfo = {
      page, // 页码
      limit // 页数
    }
    // 分页参数已拿到，剩下就是你自己调用接口的方法
  }
</script>



// 分页组件代码
<template>
  <div :class="{ hidden: hidden }" class="pagination-container scrollBar">
    <el-pagination
      :background="background"
      v-model:current-page="currentPage"

      :layout="layout"
      :page-sizes="pageSizes"
      :total="total"

      @current-change="handleCurrentChange"
