react+ant design实现Table的增、删、改

本人小白一名，第一次学习react ,该资料为本人原创，采用的是react+ant design的Tabled的一个小demo,暂时只实现了增加，删除单行，多行删除有Bug,查看详情，呕心沥血耗时一周完成，禁止抄袭，转载请先留言，

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：记住引入antd.css， 否则Table组件无法正常显示。

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) {//   构造函数
        super(props);
        this.state = {
            dataSource:[
                { key: 1, nid:1, name: "tab", gender:"男" , age: 22, schoolname: "第一中学", description: "热爱班级活动，尊敬老师"},
                { key: 2, nid:2, name: "shift", gender:"男" , age: 22, schoolname: "第一中学", description: "热爱班级活动，尊敬老师"},
                { key: 6, nid:6, name: "ctrl", gender:"男" , age: 22, schoolname: "第一中学", description: "热爱班级活动，尊敬老师"},
                { key: 4, nid:4, name: "caps lock", gender:"男" , age: 22, schoolname: "第一中学", description: "热爱班级活动，尊敬老师"},
                { key: 5, nid:5, name: "enter", gender:"女" , age: 22, schoolname: "第一中学", description: "热爱班级活动，尊敬老师"}
            ],
            index : "",
            PersonCount :0,
            selectedRowKeys:[],
            selectedRows:[],
            record : "abc"
        };
        this.onDelete = this.onDelete.bind(this);//绑定this,声明该方法需要绑定this, 直接在onClick中调用
        this.appendPerson = this.appendPerson.bind(this);
        this.handleSelectedDelete = this.handleSelectedDelete.bind(this);
       this.columns = [
            { title: "编号", dataIndex: "nid", key: "nid" ,width:"8%"},
            { title: "姓名", dataIndex: "name", key: "name" ,width:"15%"},
            { title: "性别", dataIndex: "gender", key: "gender" ,width:"10%"},
            { title: "年龄", dataIndex: "age", key: "age",width:"15%", },//render: (text, record, index) => (Math.floor(record.age/10))*10+"多岁"},
            { title: "学校", dataIndex: "schoolname", key: "schoolname",width:"15%" },
            { title: "在校表现", dataIndex: "description", key: "description" ,width:"20%"},
            { title: "操作", dataIndex: "", key: "operation", width:"32%",render: (text,record,index)=>(

                     </Popconfirm>
                    <span className="ant-divider"/>
                    <UserDetails className="user_details"  pass={record}/>
                </span>
            ) },
        ];
        }

    appendPerson(event){//得到子元素传过来的值
        let array = [];
        let count = 0;
        this.state.dataSource.forEach(function (element) {
            Object.keys(element).some(function (key) {

                    array[count] = element.nid
                }
            })
        })
        let sortData =array.sort();//对遍历得到的数组进行排序
        let MaxData = sortData[(this.state.dataSource.length)-1]//取最后一位下标的值
        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为获取的索引，后面的 1 是删除几行
            this.setState({ dataSource });
    }

    handleSelectedDelete(){
        if(this.state.selectedRowKeys.length>0){

        }
        else{

        }
    }

    render() {
        //联动选择框
       const rowSelection = {
            onChange: (selectedRowKeys, selectedRows) => {
                this.setState({//将选中的id和对象存入state
                        selectedRowKeys:selectedRowKeys,
                        selectedRows:selectedRows
                })
                console.log(selectedRows,selectedRowKeys)

module.exports = ExampleTable;

3、AddUser.jsx

import React from "react";
import {Form,Input,Button,Select,Modal} from "antd"
const FormItem = Form.Item;
const Option = Select.Option;

class  AddUser extends React.Component{//在es6中定义一个AddUser类
     constructor(props){//构造函数
         super(props);
         this.state = {

     }
    handleAdd() {
        this.setState({

        });
    }
    handleSubmit(e){//提交表单
        e.preventDefault();

                 })
                 this.props.form.resetFields();//清空提交的表单
                 //当值传递到父元素后，通过回调函数触发appendPerson方法将参数values带到父元素
                 this.props.callback(values);
             }
         })
    }

    handleClear(){

    }
    render(){

        )
    }
}
AddUser = Form.create()(AddUser); //解决了getFieldDecorator无法定义;

export default AddUser;

4、UserDetails.jsx

import React from "react"
import {Modal,Button} from "antd"
/*

 */
class  UserDetails extends React.Component{
    constructor(props){
        super(props);
        this.state={

    }
    handlePopup() {
        this.setState({

        });
    }
    handleOkOrCancel(){

        });
    }

    render(){
        return(
            <div>
                <a onClick={this.handlePopup}>详情</a>
                <Modal title={this.props.pass.name} visible={this.state.visible}
                       onOk=   {this.handleOkOrCancel} onCancel={this.handleOkOrCancel}>

                </Modal>
            </div>
        )
    }

}

export default UserDetails;

5、ExampleStyle.css

#div-right{
    width:80%;
    height:400px;
    text-Align:center;
    margin: 0 auto;
}
.div_body{
    margin-top: 0.5%;
