react tree数选择如何实现多组联动

react+antdesign使用tree数选择组件，如何实现多组联动？
想要实现的是：一个员工可能存在多个分组，比如我在分组一中勾选张三，分组二、分组三中的张三也要同步勾选上，目前后端返回数据人员id相同，这样的话就导致树结构数据混乱出现脏数据，如果设置不同的key值又会出现点击第一个分组张三不生效，但是最后一个张三会被勾中

要实现多组联动，可以考虑使用 React 的状态管理来实现。首先需要在组件的 `state` 中定义一个用于存储选中节点的数组，然后在 TreeSelect 组件中通过 `value` 属性和 `onChange` 事件进行绑定。每次勾选或取消勾选一个节点时，都更新选中节点的数组，并根据当前选中的节点自动选中其它相关节点。

下面是一个简单的示例代码：

```jsx
import React, { useState } from 'react';
import { TreeSelect } from 'antd';

const treeData = [
  {
    title: '分组一',
    value: 'group1',
    children: [
      {
        title: '员工A',
        value: 'employeeA',
      },
      {
        title: '员工B',
        value: 'employeeB',
      },
    ],
  },
  {
    title: '分组二',
    value: 'group2',
    children: [
      {
        title: '员工A',
        value: 'employeeA',
      },
      {
        title: '员工C',
        value: 'employeeC',
      },
    ],
  },
];

function App() {
  const [selectedKeys, setSelectedKeys] = useState([]);

  function handleChange(value) {
    setSelectedKeys(value);
  }

  function getRelatedKeys(key) {
    const relatedKeys = [];
    treeData.forEach(node => {
      if (node.children && node.children.some(child => child.value === key)) {
        relatedKeys.push(node.value);
      }
    });
    return relatedKeys;
  }

  function handleCheck(checkedKeys, info) {
    // 获取当前操作的节点
    const currKey = info.node.props.value;

    // 获取和当前节点相关的所有节点
    const relatedKeys = getRelatedKeys(currKey);

    // 生成最终选中的节点数组
    const finalSelectedKeys = selectedKeys.filter(key => !relatedKeys.includes(key)).concat(checkedKeys);

    // 更新选中节点数组状态
    setSelectedKeys(finalSelectedKeys);
  }

  return (
    <TreeSelect
      treeData={treeData}
      value={selectedKeys}
      onChange={handleChange}
      treeCheckable
      showCheckedStrategy="SHOW_PARENT"
      onCheck={handleCheck}
    />
  );
}

export default App;

上述代码中，通过 useState 和 setSelectedKeys 定义了选中节点的数组 selectedKeys，然后通过 value 属性和 onChange 事件将 TreeSelect 组件和 selectedKeys 绑定起来。在 handleCheck 函数中，先获取当前操作的节点和其它相关节点，然后根据当前选中的节点自动选中其它相关节点，并更新选中节点的数组状态。最终将 selectedKeys 数组作为 TreeSelect 组件的 value 属性值传入，就可以渲染出一个多组联动的 TreeSelect 组件了。
