从 API 获取新闻标题并每页显示 10 条新闻及其 ID。同样是 10 秒刷新，新的头条新闻出现。TableHead 映射内容看起来不错，但 tableBody 提供了此错误：

输入“字符串|” 日期”不可分配给类型“ReactNode”

//Init post

  url: string;
  created_at: Date;
  author: string;
}

//state of post
const [posts, setPosts] = useState<InitPost[]>([]);

//colums
const columns: readonly Column[] = [
  { id: "title", label: "Title", minWidth: 170 },
  { id: "url", label: "URL", minWidth: 150 },
  { id: "created_at", label: "Created At", minWidth: 100 },
  { id: "author", label: "Author", minWidth: 100 },
];

桌头部分: 精细

                <TableHead> …
