title: Using Angular Material table mat-text-column in a wrapper table
body: <p>I'm using Angular Material tables and I've built a wrapped table like <a href="https://github.com/angular/components/tree/master/src/material-examples/table-wrapped" rel="nofollow noreferrer">https://github.com/angular/components/tree/master/src/material-examples/table-wrapped</a>. Is there a way I can <code>mat-text-column</code> in my wrapped table? When I do the following:</p>
  
  <pre><code>&lt;wrapper-table [dataSource]="dataSource" [columns]="displayedColumns" matSort #sort="matSort"&gt;
      &lt;mat-text-column name="firstName"&gt;&lt;/mat-text-column&gt;
  &lt;/wrapper-table&gt;
  </code></pre>
  
  <p>I get <code>Error: Could not find column with id "firstName".</code></p>
