The pagination component encapsulated in this article is primarily based on ElementUi’s El-Pagination, which adds page scrolling to the table header during page switching.
Import Pagination from ‘@/components/Pagination’
Components: {Pagination},
3. Use components
<pagination
v-show="total>0"
:total="total"
:page.sync="listQuery.pageIndex"
:limit.sync="listQuery.limit"
@pagination="getList('')"
/>
Copy the code@/components/Pagination/index.vue
<template>

:layout="layout"
:page-sizes="pageSizes"
:total="total"
v-bind="$attrs"
