我有数据表和数据列表。我想显示加载图标，表示数据正在加载。我可以显示数据，但不能显示加载图标。

我的html

 <p-dataTable [value]="stuList" [rows]="10" [paginator]="true" [loading]="loading" [totalRecords]="totalRecords" [rowsPerPageOptions]="[50,100,150]" [pageLinks]="3" sortMode="multiple" [(selection)]="selectedData"  selectionMode="single" expandableRows="true">
//coulmns
</p-dataTable>

我的服务课

 import {Injectable} from '@angular/core';
import {Http, Response,Headers} from '@angular/http';
import {Student} from './student';
import 'rxjs/Rx';

@Injectable()
export class StudentService {
private headers = new Headers({'Content-Type': 'application/json'});
student:Student;
url:any='http:localhost:3002/getStudents';
constructor(private http: Http) {}
//Rest Call
getData(): Observable<Student[]>{
return this.http.get(this.url)
.map(this.extractData)
.catch(this.handleError);
}
private extractData(res: Response) {
let body = res.json();
return body.data.request as Student[];
}
}

我的桌子组件

 import { Component,OnInit, Input} from '@angular/core';
import { StudentService } from './studentservice.component'
import { Student} from './student'
import { Router }    from '@angular/router';
import 'rxjs/Rx';
import 'rxjs/add/operator/map';
import {Injectable} from '@angular/core';

@Component({
selector: 'data-grid',
templateUrl: '../app/datagrid.html',
styleUrls: ['../app/datagrid.css']
})
@Injectable()
export class StudentDataGrid implements OnInit {
datasource:Student[];
stuList:Student[];
selectedData:Student; 
@Input()
loading: boolean;
totalRecords:number;
constructor(private studentService:StudentService, private router:Router) {      }
ngOnInit() {
this.loading = true;
//Rest call
this.studentService.getData().subscribe(stuList => {
this.datasource = stuList;
this.totalRecords = this.datasource.length;
this.stuList = this.datasource;
this.loading = false;
}); 
}

我的应用程序模块类

 import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule }   from '@angular/forms';
import { HttpModule }    from '@angular/http';
import { AppRoutingModule } from './app-routing.module';
import { InMemoryWebApiModule } from 'angular-in-memory-web-api';
import { InMemoryDataService }  from './in-memory-data.service';
import { AppComponent }         from './app.component';
import {DataTableModule,SharedModule} from 'primeng/primeng';
import {DialogModule} from 'primeng/primeng';

@NgModule({
imports: [BrowserModule,FormsModule,HttpModule,InMemoryWebApiModule.forRoot(InMemoryDataService,{passThruUnknownUrl:   true}),
AppRoutingModule,DataTableModule,SharedModule,DialogModule ],
declarations: [],providers: [],bootstrap: [ AppComponent ]})
export class AppModule { }

当我试着上面的代码，显示下面的错误。

无法绑定到“加载”，因为它不是“”的已知属性。1.如果“p-dataTable”是一个角度分量，并且它有“加载”输入，则验证它是该模块的一部分。2.如果‘p’是一个Web组件，那么将"CUSTOM_ELEMENTS_SCHEMA“添加到该组件的'@NgModule.schemas‘中，以抑制此消息。

我是不是遗漏了什么？请帮帮忙
