contolling the appearence of the components

In my page there is several components,such as table,textfileds,and buttons. The problems is in display the table appears first,then a huge space. Later the textfields and buttons appear. So how can i eliminate that space? I'm using vertical layout

If you add a Table and some other components in a VerticalLayout, there should not normally be any particular space between the components, so it's hard to say what your problem could be without knowing more about the code. For example, setting the VerticalLayout to 100% height, with setFullSize() for example, it can add space between the components as it spreads them evenly to take all the space. Also setSpacing() for the layout adds space, as it should.
