title: PrimeNG treetable. Conditionally change style of row
body: <p>I would like to conditionally change the style of a row in the PrimeNG TreeTable.
  I have tried various options such as:<code>[rowStyleClass]="rowStyle()"</code></p>
  
  <p>But I get this error:
  <code>Can't bind to 'rowStyleClass' since it isn't a known property of 'p-treeTable'</code></p>
  
  <p>Any ideas on how to change the row style conditionally?</p>
