Laravel 框架 在模板页面直接输出数据,怎么在页面打开的时候显示 loading 加载

方法

public function myMerchant(Request $request){
        $service_manager = MerchantService()->getServiceManagerForRole();
        $user = MerchantService()->getMerchantList($request);
        $role_id = UserService()->getUserRole();
        return view('admin.public.loading', [
            'service_manager'=>$service_manager,
            'data'=>$user,
            'role'=>$role_id,
        ]);
    }

*模板页面循环输出数据

<tbody>
            @if($data->count())
                @foreach($data as $key=>$value)
                    <tr>
                        <td>{{ ($key+1)+(((request()->get("page") ?request()->get("page") : 1)-1) *20) }}</td>
                        <td>{{$value->name}}</td>
