這篇文章運用簡單易懂的例子給大家介紹Antd如何使用Table組件嵌套Table以及選擇框聯動,內容非常詳細,感興趣的小伙伴們可以參考借鑒,希望對大家能有所幫助。
在使用Table組件嵌套Table時,父子Table的選擇框需要聯動,即父Table選中,該行下的子Table需要全選中,某一個子Table全部選中,則該子Table所在的父Table那一行也需要選中。
父子Table聯動,就不能使用OnChange,需要使用OnSelect以及OnSelectAll手動配置。
selectedRowKeys:指定選中項的key數組
OnSelect:手動選擇/取消選擇某行的回調
OnSelect(record, selected, selectedRows)
record:選中的當前行數據
selected:選中狀態,true:選中,false:取消選中
selectedRows:選擇的數組
OnSelectAll:手動選擇/取消選擇所有行的回調
OnSelect(selected, selectedRows, changeRows)
selected:選中狀態,true:選中,false:取消選中
selectedRows:選擇的數組
changeRows:改變的所有數組
import React, { useEffect, useState } from 'react'; import { Table, } from 'antd' export default () => { const dataSource: any = [ { key: '1', title: '餐飲酒店/服務員', number: '8家門店,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: '餐飲酒店/收銀員', number: '無門店,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: '工種', dataIndex: 'title', key: 'title', }, { title: '關聯門店數', dataIndex: 'number', key: 'number', }, { title: '時間', dataIndex: 'time', key: 'time', }, ] const expandedRowRender = (record: any, index: any, indent: any, expanded: any) => { const childData = record.childData const childColumns: any = [ { title: '崗位名稱', dataIndex: 'jobTitle', key: 'jobTitle' }, { title: '招聘人數', 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> ); }
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、創建childSelectedRowKeys,parentSelectedRowKeys變量,用來存放父子Table選中的key值
const [parentSelectedRowKeys, setParentSelectedRowKeys] = useState<any>([])
const [childSelectedRowKeys, setChildSelectedRowKeys] = useState<any>([])
3、設置子Table手動選擇/取消某行的回調 onChildSelectChange
選擇單個時,當前行選中,若將該Table的所有選項全部選中,則子Table對應的父Table所在的那一行也選中
const onChildSelectChange = (record: any, selected: any, selectedRows: any) => { let childArr: any = [...childSelectedRowKeys]; //第一步 判斷selected true:選中,將key值添加到childArr,false:取消選中,將key值從childArr中移除 if (selected) { childArr.push(record.key) } else { childArr.splice(childArr.findIndex((item: any) => item === record.key), 1) } //必須去除undefined,否則selectedRows會將其他子Table中選中的key值放到數組中,但是值為undefined,如:[ undefined,1,uundefined] selectedRows = selectedRows.filter((a: any) => a !== undefined) //第二步,判斷selectedRows的長度是否為data中child的長度,相等,就將父table選中,不等就不選中 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、設置子Table手動選擇/取消選擇所有行的回調onChildSelectAll
當選擇全選時,子Table全部選中,并且該子table對應的父table行也選中,取消全選時,子Table全部取消選中,父Table行也取消選中
const onChildSelectAll = (selected: any, selectedRows: any, changeRows: any) => { //第一步:判斷selected,true:將子Table全部選中,false:將子Table全部取消選中 let childArr: any = [...childSelectedRowKeys]; if (selected) { //全選 childArr = Array.from(new Set([...childArr, ...changeRows.map((item: any) => item.key)])) } else { //取消全選 childArr = childArr.filter((item: any) => !changeRows.some((e: any) => e.key === item)) } //第二步:找到子Table對應的父Table的所在行,再判斷selected,true:將父Table所在行選中,false:將父Table所在行取消選中 for (let item of dataSource) { if (item.childData.find((d: any) => d.key === changeRows[0].key)) { let parentArr: any = [...parentSelectedRowKeys]; if (selected) { //全選 parentArr.push(item.key) } else { //取消全選 parentArr.splice(parentArr.findIndex((item: any) => item === item.key), 1) } setParentSelectedRowKeys(parentArr) break; } } setChildSelectedRowKeys(childArr) }
5、設置父Table手動選擇/取消某行的回調 onParentSelctChange
當選擇父Table某一行時,該行下的子Table全部選中,取消選擇時,該行下的子Table也全部取消選中
const onParentSelectChange = (record: any, selected: any, selectedRows: any) => { let patentArr: any = [...parentSelectedRowKeys]; let childArr: any = [...childSelectedRowKeys]; //setChildArr:選擇父Table下的所有子選項 let setChildArr = dataSource.find((d: any) => d.key === record.key).childData.map((item: any) => item.key) //第一步 判斷selected true:選中,false,取消選中 if (selected) { //第二步,父Table選中,子Table全選中(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取消選中,子Table全取消選中(針對childArr,過濾掉取消選中的父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,設置父,子的SelectedRowKeys setParentSelectedRowKeys(patentArr) setChildSelectedRowKeys(childArr) }
6、設置父Table手動選擇/取消選擇所有行的回調onParentSelectAll
全選時,父Table全部選中,所有對應的子Table也全部選中。取消全選時,父Table取消選中,所有子Table也取消選中
const onParentSelectAll = (selected: any, selectedRows: any, changeRows: any) => { let patentArr: any = [...parentSelectedRowKeys]; let setChildArr: any = []; //將改變的父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)] }); //第一步判斷selected true:全選,false:取消全選 if (selected) { //第二步:父Table選中,子Table全選中,設置子Table的SelectedRowKeys patentArr = Array.from(new Set([...patentArr, ...changeRows.map((item: any) => item.key)])) setChildSelectedRowKeys(setChildArr) } else { //第二步:父Table取消選中,子Table全取消選中,設置子Table的SelectedRowKeys patentArr = patentArr.filter((item: any) => !changeRows.some((e: any) => e.key === item)) setChildSelectedRowKeys([]) } //第三步:設置父Table的SelectedRowKeys setParentSelectedRowKeys(patentArr) }
這樣,父子Table的選擇框聯動就完成了,
注意:dataSource數據格式根據自己的格式而定
