编写以下 DataTable 组件

import React, {useEffect, useState} from "react";
import MUIDataTable from "mui-datatables";
import axios from 'axios';

function DataTable() {
    const [posts, setPost] = useState([]);
    const [isLoading, setIsLoading] = useState(false);
    let signal = axios.CancelToken.source();

    useEffect(() => {
        setIsLoading(true);
        let isSubscribed = true;
        axios.get(`https://jsonplaceholder.typicode.com/posts`, {
            cancelToken: signal.token,
        })
            .then(res => {
                const posts = res.data;
                setPost(posts);
                setIsLoading(false);

            }).catch(err => {
            setIsLoading(false);
            console.log(err);
        });
        return function cleanup() {
            isSubscribed = false;
            signal.cancel('Api is being canceled');
        }
    }, []);

    const columns = ["id", "title", "body"];

    const options = {
        filterType: "dropdown",
        responsive: "scroll"
    };

    return (
        <MUIDataTable
            title={"Posts"}
            data={posts}
            columns={columns}
            options={options}
        />
    );
}

export default DataTable;

并在 app.js 中使用 DataTable 组件

import React from "react";
import ReactDOM from 'react-dom';
import DataTable from "./DataTable";

class App extends React.Component {
  render() {
    return (
        <DataTable/>
    );
  }
}
ReactDOM.render(<App />, document.getElementById("root"));

export default App;
