问题：
我在 Stackblitz 和本地开发计算机上使用的相同代码，它不起作用。

我缺少什么部分？

反应-table.d.tsx

import {
  UseSortByColumnOptions,
  UseSortByColumnProps,
  UseSortByInstanceProps,
  UseSortByOptions,
  UseSortByState,
} from 'react-table';

declare module 'react-table' {
  export interface TableOptions<D extends object> extends UseSortByOptions<D> {}

  export interface TableInstance<D extends object = {}>
    extends UseSortByInstanceProps<D> {}

  export interface TableState<D extends object = {}>
    extends UseSortByState<D> {}

  export interface Column<D extends object = {}>
    extends UseSortByColumnOptions<D> {}

  export interface ColumnInstance<D extends object = {}>
    extends UseSortByColumnProps<D> {}
}

Answer 1

您输入的状态有误，TypeScript 会警告您。

当您在 useState 中传递默认值 [] 时，TypeScript 假定数组中永远不会有任何内容，因此是 never[] 类型。您需要执行 useState<Data[]>([])，这将告诉 TypeScript 状态的正确类型。
