vue elementUI 分页组件封装Demo 可二次复用 分

最常用参数都做了处理

:page-size.sync="pageSize"
:layout="layout"
:page-sizes="pageSizes"
:total="total"

pagination.vue

<style scoped>
.pagination-container {
  background: #fff;
  padding: 32px 16px;
}
.pagination-container.hidden {
  display: none;
}
</style>

使用

<pagination 
:page="currentPage" 
:limit="pageSize" 
:total="total" 
@pagination="pagination" />
