Php laravel 5.4控制器显示数据库中的所有内容，而不是跳过

您好，感谢您点击此问题/声明

目标是创建一个“库”，只显示数据库中的每个“标题”一次。我们只需要显示21个“标题”一次和分页

下面是页面外观的屏幕截图链接

这是控制器

控制器

 return view('library.index')
           ->with('titles', Title::all())
           ->with('first_title', Title::orderBy('created_at', 'desc')->first())
           ->with('second_title', Title::orderBy('created_at', 'desc')->skip(1)->take(1)->get()->first())
           ->with('third_title', Title::orderBy('created_at', 'desc')->skip(2)->take(1)->get()->first());
} 

这是显示标题的页面
