title: VAADIN - set full height of tab content
body: <p>I have a <code>TabSheet</code> and a tab item.
  There is a table inside the tab.
  I have set all height to <code>setFullSize</code> but the height of the table does not occupy the whole tab.</p>
  
  <p>Code is here:</p>
  
  <pre><code>public class GvApplication extends Application {
      private static Logger log = Logger.getLogger(GvApplication.class.getName());
  
      Window mainWindow;
      TabSheet tabsheet;
  
      @Override
      public void init() {
          setTheme("gv");
  
          mainWindow = new Window("Test");
          mainWindow.getContent().setHeight("100%");
  
          tabsheet = new TabSheet();
          tabsheet.setSizeFull();
  
          mainWindow.addComponent(tabsheet);
  
          initSMSTab();
  
          setMainWindow(mainWindow);
      }
  
      private void initSMSTab() {
          VerticalLayout tab = new VerticalLayout();
          tab.setMargin(true);
  
          Table table = new Table("Naam");
  
          table.setWidth("100%");
          table.setHeight("100%");
  
          table.setSizeFull();
          tab.addComponent(table);
  
          tabsheet.addTab(tab);
  
          Tab smsTab = tabsheet.getTab(tab);
          smsTab.setCaption("SMS");
      }
  }
  </code></pre>
  
  <p>There is a lot of space left under the table. How can I make table use the whole content of the tab?</p>
