Angular2异步嵌套数据

export class DiagnosisComponent {

  headers: Array<String> = ["hello world","hello world"];
  table: Observable<TableData>;

  constructor(private eventService: EventService) {
    this.table = this.eventService.getDiagnosisEvents();
    this.table.subscribe(console.log.bind(console));
  }

}

这是TableData类

export class TableData {

  content: Array<any>;
  paging: Paging;

  constructor(obj: any) {

    this.paging = {
      size: obj.size,totalElements: obj.totalElements,currentPage: 1
    };

    this.content = obj.content;

  }

}

export interface Paging {
  size: number;
  totalElements: number;
  currentPage: number;
}

现在我想将table.content数组绑定到带有异步管道的* ngFor.我的问题是我需要获取嵌套数据,而不是TableData本身.

<div class="row">

  <vpscout-filter></vpscout-filter>

  <table class="table">
    <thead>
    <tr><th *ngFor="let header of headers">{{header | translate}}</th></tr>
    </thead>
    <tbody>
    <tr *ngFor="let row of table | async ">
      <td>test</td>
    </tr>
    </tbody>
  </table>

</div>

将* ngFor更改为< tr * ngFor =“let table of table | async”>不起作用.
