本人小白一名，第一次學習react ,該資料為本人原創，采用的是react+ant design的Tabled的一個小demo,暫時只實現了增加，刪除單行，多行刪除有Bug,查看詳情，嘔心瀝血耗時一周完成，禁止抄襲，轉載請先留言，
1、main.jsx
import React from 'react';import ReactDom from 'react-dom';import ExampleTable from './ExampleTable.jsx' ReactDom.render( <ExampleTable/>, document.getElementById('AppRoot'));2、ExampleTable.jsx, 注：記住引入antd.css， 否則Table組件無法正常顯示。
import React from 'react';import { Table,Button,Input,Icon,Popconfirm,Alert } from 'antd';import AddUser from './AddUser.jsx'import UserDetails from './UserDetails.jsx' class ExampleTable extends React.Component { constructor(props) {// 構造函數 super(props); this.state = { dataSource:[ { key: 1, nid:1, name: 'tab', gender:'男' , age: 22, schoolname: '第一中學', description: '熱愛班級活動，尊敬老師'}, { key: 2, nid:2, name: 'shift', gender:'男' , age: 22, schoolname: '第一中學', description: '熱愛班級活動，尊敬老師'}, { key: 6, nid:6, name: 'ctrl', gender:'男' , age: 22, schoolname: '第一中學', description: '熱愛班級活動，尊敬老師'}, { key: 4, nid:4, name: 'caps lock', gender:'男' , age: 22, schoolname: '第一中學', description: '熱愛班級活動，尊敬老師'}, { key: 5, nid:5, name: 'enter', gender:'女' , age: 22, schoolname: '第一中學', description: '熱愛班級活動，尊敬老師'} ], index : '', PersonCount :0, selectedRowKeys:[], selectedRows:[], record : 'abc' }; this.onDelete = this.onDelete.bind(this);//綁定this,聲明該方法需要綁定this, 直接在onClick中調用 this.appendPerson = this.appendPerson.bind(this); this.handleSelectedDelete = this.handleSelectedDelete.bind(this); this.columns = [ { title: '編號', dataIndex: 'nid', key: 'nid' ,width:'8%'}, { title: '姓名', dataIndex: 'name', key: 'name' ,width:'15%'}, { title: '性別', dataIndex: 'gender', key: 'gender' ,width:'10%'}, { title: '年齡', dataIndex: 'age', key: 'age',width:'15%', },//render: (text, record, index) => (Math.floor(record.age/10))*10+"多歲"}, { title: '學校', dataIndex: 'schoolname', key: 'schoolname',width:'15%' }, { title: '在校表現', dataIndex: 'description', key: 'description' ,width:'20%'}, { title: '操作', dataIndex: '', key: 'operation', width:'32%',render: (text,record,index)=>( <span> <Popconfirm <a <Icon type="delete"/></a> </Popconfirm> <span className="ant-divider"/> <UserDetails className="user_details" pass={record}/> </span> ) }, ]; } appendPerson(event){//得到子元素傳過來的值 let array = []; let count = 0; this.state.dataSource.forEach(function (element) { Object.keys(element).some(function (key) { if (key === 'nid') { count++; array[count] = element.nid } }) }) let sortData =array.sort();//對遍歷得到的數組進行排序 let MaxData = sortData[(this.state.dataSource.length)-1]//取最后一位下標的值 event.key=MaxData+1; event.nid = MaxData+1; this.setState({ dataSource:[...this.state.dataSource,event] }) } onDelete(index){ console.log(index) const dataSource = [...this.state.dataSource]; dataSource.splice(index, 1);//index為獲取的索引，后面的 1 是刪除幾行 this.setState({ dataSource }); } handleSelectedDelete(){ if(this.state.selectedRowKeys.length>0){ console.log(...this.state.selectedRowKeys) const dataSource = [...this.state.dataSource] dataSource.splice(this.state.selectedRows,this.state.selectedRows.length) this.setState({ dataSource }); } else{ } } render() { //聯動選擇框 const rowSelection = { onChange: (selectedRowKeys, selectedRows) => { this.setState({//將選中的id和對象存入state selectedRowKeys:selectedRowKeys, selectedRows:selectedRows }) console.log(selectedRows,selectedRowKeys) }, onSelect: (record, selected, selectedRows) => { //console.log( record, ` selected :${selected}`,`selectedRows:${selectedRows}`); }, onSelectAll: (selected, selectedRows, changeRows) => { //console.log(selected, selectedRows, changeRows); }, getCheckboxProps: record => ({ disabled: record.name === 'Disabled User', // Column configuration not to be checked }), } return ( <div className="div_body"> <div id="div_left"></div> <div id="div-right"> <div className="table_oftop"> <Button type="primary" icon="search" style={{float:"right",marginLeft:10}}>查詢</Button> <Input placeholder="input search text" style ={{width:300,float:"right"}}/> <div id="add_delete"> <Button type="primary" className="selectedDelete" onClick={this.handleSelectedDelete}>刪除所選</Button> <AddUser className="add_user_btn" callback={this.appendPerson}/> </div> </div> <Table columns={this.columns} dataSource={this.state.dataSource} className="table" rowSelection={rowSelection} scroll ={{y:400}}/> </div> </div> ); }}module.exports = ExampleTable;3、AddUser.jsx

import React from 'react'import {Modal,Button} from 'antd'/* */class UserDetails extends React.Component{ constructor(props){ super(props); this.state={ visible:false } this.handlePopup = this.handlePopup.bind(this); this.handleOkOrCancel = this.handleOkOrCancel.bind(this); } handlePopup() { this.setState({ visible: true }); } handleOkOrCancel(){ this.setState({ visible: false }); } render(){ return( <div> <a onClick={this.handlePopup}>詳情</a> <Modal onOk= {this.handleOkOrCancel} onCancel={this.handleOkOrCancel}> <p>姓名： {this.props.pass.name}</p> <p>性別： {this.props.pass.gender}</p> <p>年齡： {this.props.pass.age}</p> <p>就讀學校： {this.props.pass.schoolname}</p> <p>在校表現： {this.props.pass.description}</p> </Modal> </div> ) } } export default UserDetails;5、ExampleStyle.css
