在angular中使用键值管道时如何跳过ngFor中的特定键值对

<div *ngFor="let item of items | keyvalue">
  {{item.key}}: {{item.value}}
</div>

<div *ngFor="let item of items | keyvalue">
  <ng-container *ngIf="item.key !== 'skipKey'">
    {{item.key}}: {{item.value}}
  </ng-container>
</div>

<div *ngFor="let item of items | keyvalue">
  <ng-container *ngIf="item.key !== 'skipKey1' && item.key !== 'skipKey2'">
    {{item.key}}: {{item.value}}
  </ng-container>
</div>
