title: Can I use the lazy-option of the Angular PrimeNG treeTable without virtual scroll?
body: <p>Hey guys i stumbled about some problems with the lazy loading option of the prime ng treeTable. I need to use the lazyLoad event (Output property "onLazyLoad") without the virtual scroller behavior. Is this somehow supported by the treeTable component?</p>
  
  <p>Something like this:</p>
  
  <pre><code>&lt;p-treeTable [value]="virtualFiles" [columns]="cols" [scrollable]="true" [rows]="20" 
      [virtualRowHeight]="34" [lazy]="true" (onLazyLoad)="loadNodes($event)"
      [totalRecords]="totalRecords" scrollHeight="400px"&gt;
  &lt;/p-treeTable&gt;
  </code></pre>
  
  <p>If it's not possible to use lazy loading without the virtual scroller it would be okay if I at least could prevent it from destroying the previous loaded Elements.</p>
  
  <p>I already tried setting the rows-property to the length of the values-array to prevent fetching more data when scrolling upwards.</p>
  
  <p>Would be great if someone could help me with this.</p>
