Restrict number of rows in table view

Question

Can a table view has only as many rows as the actual rows in the underlying data structure. Actually, I have a table view with less than 5 rows, but the tableview shows like 15+ rows with the rest of the rows as blank(alternative colors for each empty rows). I know there is a style which can be applied to make the remaining empty rows show with white background. However, the height of the table view doesn't reduce to show only the actual number of rows. Is there a way we can restrict the height of the table view to the height of actual rows it has?
Thanks.

Hi. Add a listener to your data. Use prefheight to restrict the table height:
        table.setPrefHeight(data.size() * 25 + 25);  
        data.addListener(new ListChangeListener<Person> ()  {
            public void onChanged(ListChangeListener.Change<? extends Person> c) {
               table.setPrefHeight(data.size() * 25 + 25);
        });It works only when data.size() * 25 + 25 < scene.height
