React ProTable表格实时更新数据用函数组件ts怎么实现

在函数组件中实现实时更新数据可以使用React Hooks中的useState和useEffect。

首先，定义一个state用来存储表格数据，使用useState初始化为空数组：

const [tableData, setTableData] = useState([]);

然后，在useEffect中实现数据的实时更新，可以使用setTimeout模拟异步请求：

useEffect(() => {
  const timer = setTimeout(() => {
    // 模拟异步请求数据
    const data = fetchData();
    setTableData(data);
  }, 1000);

  return () => clearTimeout(timer);
}, [tableData]);

这样，每次tableData发生变化时，useEffect会重新执行，从而实现实时更新数据。

完整代码示例：

import React, { useState, useEffect } from "react";
import ProTable from "@ant-design/pro-table";

interface TableData {
  key: string;
  name: string;
  age: number;
  address: string;
}

const fetchData = (): TableData[] => {
  return [
    {
      key: "1",
      name: "John Brown",
      age: 32,
      address: "New York No. 1 Lake Park",
    },
    {
      key: "2",
      name: "Jim Green",
      age: 42,
      address: "London No. 1 Lake Park",
    },
    {
      key: "3",
      name: "Joe Black",
      age: 32,
      address: "Sidney No. 1 Lake Park",
    },
  ];
};

const TableDemo: React.FC = () => {
  const [tableData, setTableData] = useState<TableData[]>([]);

  useEffect(() => {
    const timer = setTimeout(() => {
      const data = fetchData();
      setTableData(data);
    }, 1000);

    return () => clearTimeout(timer);
  }, [tableData]);

  const columns = [
    {
      title: "Name",
      dataIndex: "name",
    },
    {
      title: "Age",
      dataIndex: "age",
    },
    {
      title: "Address",
      dataIndex: "address",
    },
  ];

  return (
    <ProTable<TableData>
      columns={columns}
      dataSource={tableData}
      search={false}
      pagination={false}
    />
  );
};

export default TableDemo;
