分页功能

在这里插入图片描述

分页组件有两种

table组件自带分页

<TableborderedrowKey="userId"rowSelection={{ type: 'checkbox' }}pagination={{position: ['bottomRight'],pageSize: pagination.pageSize,current: pagination.current,showQuickJumper: true,showSizeChanger: true,onChange: (page, pageSize) => {setPagination({current: page,pageSize})}}}dataSource={data}
/>

分页组件

<PaginationpageNum={pagination.pageNum}pageSize={pagination.pageSize}total={pagination.total}onChange={(pageNum: number, pageSize: number) => {setPagination({current: page,pageSize})}}
/>

接口参数

{pageNum: 1,pageSize: 10,userId: '',userName: '',state: ''
}

分页类型

export interface PageParams {pageNum: number | undefinedpageSize?: number | undefined
}

用户列表参数类型

export interface Params extends PageParams {userId?: numberuserName?: stringstate?: number
}

模拟列表数据

const list = Array.from({length:20}).fill({}).map((item:any)=>{item = {...data.list[0]}item.userId = Math.random()return item})

分页触发方式

进入页面，模拟初始化列表
点击搜索，初始化列表
点击页码，更新列表
点击每页条数，更新列表
