title: Animate new items in a TableView
body: <p>I'm using a <code>TableView</code> to display the contents of an SQLite database. The user clicks one of the checkable buttons and the right table is read through the <code>LocalStorage</code> API. Thus, the model is always new.</p>
  
  <p>Because the model is always new, the loading of the new table isn't visually attractive (all the entries are shown at once).</p>
  
  <p>My idea was to animate the height of the row when it's added (in a linear way from 0)</p>
  
  <p>Can this be done without reimplementing the <code>rowDelegate</code> from scratch?</p>
