无法在后续数据获取时触发setState with react with papa parse以将新属性传递给重新渲染子组件？

import React, { Component } from "react";
import Papa from "papaparse";

class ParentComponent extends Component {
  constructor(props) {
    super(props);
    this.state = {
      data: [], // 存储解析后的数据
      isDataLoaded: false // 数据是否已加载
    };
  }

  componentDidMount() {
    this.loadData(); // 在组件加载后加载数据
  }

  componentDidUpdate(prevProps, prevState) {
    if (!prevState.isDataLoaded && this.state.isDataLoaded) {
      // 检查数据是否已加载
      this.setState({ isDataLoaded: false }); // 重置数据加载状态
      this.updateChildComponent(); // 更新子组件
    }
  }

  loadData() {
    Papa.parse("data.csv", {
      download: true,
      complete: (results) => {
        this.setState({ data: results.data, isDataLoaded: true });
      }
    });
  }

  updateChildComponent() {
    // 更新子组件的逻辑
  }

  render() {
    return <div>ParentComponent</div>;
  }
}

export default ParentComponent;
