javascript - 如何在 HOC 组件中正确使用泛型类型？

Question

这是我的父组件（网格），（这里我传递了更多 hoc 使用的道具，但我在这里省略了它们）：

<QuickBooksTable itemList={quickBooksList} />

这是表格组件：

export const QuickBooksTable = withIntegrationTable(props: : WithIntegrationTableChildProps & WithIntegrationTableProps) => ...

这是临时的：

export function withIntegrationTable<T extends WithIntegrationTableProps>(Component: React.ComponentType<T>) {
return (
    {
      itemList,
      ...props
    }: WithIntegrationTableProps & T
  ) => {
    const [state, setState] = useState<WithIntegrationTableState>({
      tableItems: new Array<any>(),
      selectedItems: new Set<string>(),
      isAllItemsSelected: false
    });

    useEffect(() => {
      const tableItems = mapItemList(itemList, currentUser);
      setState({
        ...state,
        tableItems
      });
    }, [itemList]);

    <Component {...props as T}
               tableState={state}
    />
  }
}

但是当它编译时它说：Element QuickBooksTable doesn't have required attribute (here is another props name). 我应该如何使用类型和泛型来消除这个错误？我试图阅读文档，但我不明白我做错了什么。

我认为这就是你试图实现的目标。

import React from 'react';
import { useEffect, useState } from 'react';

interface WithIntegrationTableProps {
    itemList: string[]
}

interface WithIntegrationTableState { }

export const withIntegrationTable = <P extends WithIntegrationTableState>(
    Component: React.ComponentType<P & { 
        tableState: WithIntegrationTableState
    }>
): React.FC<P & WithIntegrationTableProps> => ({
    itemList,
    ...props
}: WithIntegrationTableProps) => {
    const mapItemList = (itemList: any, currentUser: any) => {

    }

    const [state, setState] = useState<WithIntegrationTableState>({
        tableItems: new Array<any>(),
        selectedItems: new Set<string>(),
        isAllItemsSelected: false
    });

    useEffect(() => {
        const tableItems = mapItemList(itemList, null);
        setState({
            ...state,
            tableItems
        });
    }, [itemList]);

    return <Component {...props as P} tableState={state} />
}

export const QuickBooksTable = withIntegrationTable(({ ...props }) => {
    console.log(props.tableState)
    return <div>
        test
    </div>
})

const App = () => {
    return <QuickBooksTable itemList={[]} />
}

export default App
