用antd的List做动态滚动展示

　　项目中需要做一个类似于Table的展示列表,但是需要循环滚动播放列表内容

 　　不多说直接上代码:

js部分:

export default class RealTime extends PureComponent {
    state = {
        sectionDomHeight: 0
    }

    componentDidMount() {
        this.computeHeight();
    }
    computeHeight = () => {
        setTimeout(() => {
            let sectionDomHeight = this.sectionDom && this.sectionDom.offsetHeight || 0;
            this.setState({
                sectionDomHeight
            })
        }, 0)
    }
    handleSection = n => {
        this.sectionDom = n;
    };

    render() {
        const { getLoading } = this.props;

        let list = []
        for(let i=0;i<12;i++){
            list.push({
                'Intl_time_of_occurrence': '2020-07-22 18:55:50',
                'Intl_file_name': i,
                'Intl_source_ip': '192.168.1.201',
                'Intl_dection_ip': '27.115.124.142',

                'Intl_protocol': 'HTTP',
                'Intl_file_type': 'Word',
                'Intl_sensitivity': '高敏感',
                'Intl_manner': '上传',
            })
        }
        const messageList = (
            <List
                bordered={false}
                dataSource={list}
                renderItem={(item, index) => {
                    return <List.Item>
                        <span className={styles.texts}>
                            <span>{item.Intl_time_of_occurrence}</span>
