title: How to highlight a selected row in *ngFor?
body: <p>I couldn't find something that will help me to solve this issue in Angular2. I'd like to set a css class when I select a row. (without using jQuery)</p>
  
  <pre><code>&lt;table class="table table-bordered table-condensed table-hover"&gt;
      &lt;thead&gt;
          &lt;tr&gt;
              &lt;th&gt;Name&lt;/th&gt;
              &lt;th&gt;Email&lt;/th&gt;
              &lt;th&gt;Website&lt;/th&gt;
          &lt;/tr&gt;
      &lt;/thead&gt;
      &lt;tbody&gt;
          &lt;tr *ngFor="let item of companies"  (click)="selectedCompany(item, $event)"&gt;
              &lt;td&gt;{{item.name}}&lt;/td&gt;
              &lt;td&gt;{{item.email}}&lt;/td&gt;
              &lt;td&gt;{{item.website}}&lt;/td&gt;
          &lt;/tr&gt;
      &lt;/tbody&gt;   
  &lt;/table&gt; 
  </code></pre>
  
  <p>I'm using Angular2 final release</p>
