View[]
和 app.component.ts
<table class="table">
<thead>
<tr>
<th scope="col">#</th>
<th scope="col">First</th>
<th scope="col">Last</th>
<th scope="col">Title</th>
</tr>
</thead>
<tbody>
<tr *ngFor="let tableRow of table" (click)="open(tableRow)">
<th scope="row">{{tableRow.id}}</th>
<td>{{tableRow.first}}</td>
<td>{{tableRow.last}}</td>
<td>{{tableRow.title}}</td>
</tr>
</tbody>
</table>
<div *ngIf="bellowContent">
<p>id: {{ bellowContent.id }}</p>
<p>first: {{ bellowContent.first }}</p>
<p>last: {{ bellowContent.last }}</p>
<p>title: {{ bellowContent.title }}</p>
