title: JavaFx: TableView - unbind all properties
body: <p>I have a <code>TableView</code> and the columns for it I create like this:</p>
  
  <pre><code>TableColumn&lt;Foo,String&gt; fieldColumn=new TableColumn("field");
  fieldColumn.setCellValueFactory(data-&gt;data.getValue().getFieldProperty());
  tableView.add(fieldColumn);
  </code></pre>
  
  <p>Now I want to destroy my <code>tableView</code> but I want to continue to use all <code>foos</code>. That's why I want to unbind <code>foos</code>' properties from table/column. How to do it?</p>
