im试图在viewCell内制作一个可扩展的表格视图
export default function Dashboard() {
const {user, isLoggedIn} = useContext(AuthContext)
if (isLoggedIn){
return (
<div className="Dashboard">El email es {user.email}</div>
);
}
return (<div>User is not logged in</div>);
}
您每次用户选择激活的某些单元格时都会看到

如果用户按第0行，它将激活代码
与
相同覆盖func tableView（_ tableView：UITableView，cellForRowAt indexPath：IndexPath）-> UITableViewCell {
但是当我尝试设置
重写func tableView（_ tableView：UITableView，numberOfRowsInSection部分：Int）-> Int {
并使其崩溃索引超出范围
主要问题是无法像im做扩展一样在另一个单元中归档信息，我想再次归档 tableViewDataInside 这是我的信息，但是我可以使它工作
