如何在angular 6中使用*ngFor绑定对象数组

items = [
  { name: 'Item 1', value: 1 },
  { name: 'Item 2', value: 2 },
  { name: 'Item 3', value: 3 }
];

<ul>
  <li *ngFor="let item of items">{{ item.name }} - {{ item.value }}</li>
</ul>

<ul>
  <li *ngFor="let item of items; let i = index">{{ i }} - {{ item.name }} - {{ item.value }}</li>
</ul>

<ul>
  <li *ngFor="let item of items">
    <ng-container *ngIf="item.value > 1">{{ item.name }} - {{ item.value }}</ng-container>
  </li>
</ul>
