这篇文章主要介绍了Antd的Table组件嵌套Table以及选择框联动操作,具有很好的参考价值,希望对大家有所帮助。一起跟随长沙网络推广过来看看吧

一、需求

在使用Table组件嵌套Table时,父子Table的选择框需要联动,即父Table选中,该行下的子Table需要全选中,某一个子Table全部选中,则该子Table所在的父Table那一行也需要选中。

二、Table的rowSelection配置

父子Table联动,就不能使用OnChange,需要使用OnSelect以及OnSelectAll手动配置。

selectedRowKeys:指定选中项的key数组

OnSelect:手动选择/取消选择某行的回调

OnSelect(record, selected, selectedRows)

record:选中的当前行数据

selected:选中状态,true:选中,false:取消选中     

selectedRows:选择的数组

OnSelectAll:手动选择/取消选择所有行的回调      

OnSelect(selected, selectedRows, changeRows)       

selected:选中状态,true:选中,false:取消选中      

selectedRows:选择的数组  

changeRows:改变的所有数组

三、根据antd文档搭建Table嵌套Table界面

import React, { useEffect, useState } from 'react';
import { Table, } from 'antd'
export default () => {
 const dataSource: any = [
 {
  key: '1',
  title: '餐饮酒店/服务员',
  number: '8家门店,共8人',
  time: '2020.05.25 15:35',
  childData: [
  {
   key: '1.1',
   jobTitle: '大桶大足浴-保安',
   num: '2人',
  },
  {
   key: '1.2',
   jobTitle: '大桶大足浴-保安',
   num: '5人',
  },
  ]
 },
 {
  key: '2',
  title: '餐饮酒店/收银员',
  number: '无门店,共5人',
  time: '2020.06.06 11:35',
  childData: [
  {
   key: '2.1',
   jobTitle: '大桶大足浴',
   num: '0人',
  },
  {
   key: '2.2',
   jobTitle: '大桶大足浴',
   num: '1人',
  },
  ]
 },
 ]
 const parentColumns: any = [
 {
  title: '工种',
  dataIndex: 'title',
  key: 'title',
 },
 {
  title: '关联门店数',
  dataIndex: 'number',
  key: 'number',
 },
 {
  title: '时间',
  dataIndex: 'time',
  key: 'time',
 },
 ]
 const expandedRowRender = (record: any, index: any, indent: any, expanded: any) => {
 const childData = record.childData
 const childColumns: any = [
  {
  title: '岗位名称',
  dataIndex: 'jobTitle',
  key: 'jobTitle'
  },
  {
  title: '招聘人数',
  dataIndex: 'num',
  key: 'num'
  },
 ]
 return <Table columns={childColumns} dataSource={childData} pagination={false} rowSelection={childRowSelection} />
 }
 return (
 <div>
  <Table columns={parentColumns} dataSource={dataSource} expandable={{ expandedRowRender }} rowSelection={parentRowSelection} />
 </div>
 );
}

四、开始配置rowSelection

1、配置父子Table的rowSelection

 const childRowSelection = {
 selectedRowKeys: childSelectedRowKeys,
 onSelect: onChildSelectChange,
 onSelectAll: onChildSelectAll
 }
 const parentRowSelection = {
 selectedRowKeys: parentSelectedRowKeys,
 onSelect: onParentSelectChange,
 onSelectAll: onParentSelectAll,
 }

2、创建childSelectedRowKeys,parentSelectedRowKeys变量,用来存放父子Table选中的key值

const [parentSelectedRowKeys, setParentSelectedRowKeys] = useState<any>([])

const [childSelectedRowKeys, setChildSelectedRowKeys] = useState<any>([])

3、设置子Table手动选择/取消某行的回调 onChildSelectChange

选择单个时,当前行选中,若将该Table的所有选项全部选中,则子Table对应的父Table所在的那一行也选中

 const onChildSelectChange = (record: any, selected: any, selectedRows: any) => {
 let childArr: any = [...childSelectedRowKeys];
 //第一步 判断selected true:选中,将key值添加到childArr,false:取消选中,将key值从childArr中移除
 if (selected) {
  childArr.push(record.key)
 } else {
  childArr.splice(childArr.findIndex((item: any) => item === record.key), 1)
 }
  //必须去除undefined,否则selectedRows会将其他子Table中选中的key值放到数组中,但是值为undefined,如:[ undefined,1,uundefined]
 selectedRows = selectedRows.filter((a: any) => a !== undefined) 
 //第二步,判断selectedRows的长度是否为data中child的长度,相等,就将父table选中,不等就不选中
 for (let item of dataSource) {
  if (item.childData.find((d: any) => d.key === record.key)) {
  let parentArr: any = [...parentSelectedRowKeys];
  if (item.childData.length === selectedRows.length) {
   parentArr.push(item.key)
  } else {
   if (parentArr.length && parentArr.find((d: any) => d === item.key)) {
   parentArr.splice(parentArr.findIndex((item1: any) => item1 === item.key), 1)
   }
  }
  setParentSelectedRowKeys(parentArr)
  break;
  }
 }
 setChildSelectedRowKeys(childArr)
 }

4、设置子Table手动选择/取消选择所有行的回调onChildSelectAll

当选择全选时,子Table全部选中,并且该子table对应的父table行也选中,取消全选时,子Table全部取消选中,父Table行也取消选中

 const onChildSelectAll = (selected: any, selectedRows: any, changeRows: any) => {
 //第一步:判断selected,true:将子Table全部选中,false:将子Table全部取消选中
 let childArr: any = [...childSelectedRowKeys];
 if (selected) {
  //全选
  childArr = Array.from(new Set([...childArr, ...changeRows.map((item: any) => item.key)]))
 } else {
  //取消全选
  childArr = childArr.filter((item: any) => !changeRows.some((e: any) => e.key === item))
 }
  //第二步:找到子Table对应的父Table的所在行,再判断selected,true:将父Table所在行选中,false:将父Table所在行取消选中
 for (let item of dataSource) {
  if (item.childData.find((d: any) => d.key === changeRows[0].key)) {
  let parentArr: any = [...parentSelectedRowKeys];
  if (selected) {
   //全选
   parentArr.push(item.key)
  } else {
   //取消全选
   parentArr.splice(parentArr.findIndex((item: any) => item === item.key), 1)
  }
  setParentSelectedRowKeys(parentArr)
  break;
  }
 }
 setChildSelectedRowKeys(childArr)
 }

5、设置父Table手动选择/取消某行的回调 onParentSelctChange

当选择父Table某一行时,该行下的子Table全部选中,取消选择时,该行下的子Table也全部取消选中

 const onParentSelectChange = (record: any, selected: any, selectedRows: any) => {
 let patentArr: any = [...parentSelectedRowKeys];
 let childArr: any = [...childSelectedRowKeys];
 //setChildArr:选择父Table下的所有子选项
 let setChildArr = dataSource.find((d: any) => d.key === record.key).childData.map((item: any) => item.key)
 //第一步 判断selected true:选中,false,取消选中
 if (selected) {
  //第二步,父Table选中,子Table全选中(全部整合到一起,然后去重)
  patentArr.push(record.key)
  childArr = Array.from(new Set([...setChildArr, ...childArr]))
 } else {
  //第二步,父Table取消选中,子Table全取消选中(针对childArr,过滤掉取消选中的父Table下的所有子Table的key)
  patentArr.splice(patentArr.findIndex((item: any) => item === record.key), 1)
  childArr = childArr.filter((item: any) => !setChildArr.some((e: any) => e === item))
 }
 //第三步,设置父,子的SelectedRowKeys
 setParentSelectedRowKeys(patentArr)
 setChildSelectedRowKeys(childArr)
 }

6、设置父Table手动选择/取消选择所有行的回调onParentSelectAll

全选时,父Table全部选中,所有对应的子Table也全部选中。取消全选时,父Table取消选中,所有子Table也取消选中

 const onParentSelectAll = (selected: any, selectedRows: any, changeRows: any) => {
 let patentArr: any = [...parentSelectedRowKeys];
 let setChildArr: any = [];
  //将改变的父Table下的子Table下的key都添加到setChildArr中
 changeRows.forEach((e: any) => {
  setChildArr = [...setChildArr, ...e.childData.map((item: any) => item.key)]
 });
 //第一步判断selected true:全选,false:取消全选
 if (selected) {
  //第二步:父Table选中,子Table全选中,设置子Table的SelectedRowKeys
  patentArr = Array.from(new Set([...patentArr, ...changeRows.map((item: any) => item.key)]))
  setChildSelectedRowKeys(setChildArr)
 } else {
  //第二步:父Table取消选中,子Table全取消选中,设置子Table的SelectedRowKeys
  patentArr = patentArr.filter((item: any) => !changeRows.some((e: any) => e.key === item))
  setChildSelectedRowKeys([])
 }
 //第三步:设置父Table的SelectedRowKeys
 setParentSelectedRowKeys(patentArr)
 }

这样,父子Table的选择框联动就完成了,

注意:dataSource数据格式根据自己的格式而定
