How to load a page partially, bits by bits

I am pretty new to Vaadin.

Say my page contains a summary area at the top and a detailed table at the bottom. The table would take longer to load all the data.
How to make the page show up with the summary data first without fully loading the table yet at the bottom of the page. Use sees a hour glass while the table is loading.

Right now the problem is the page does not show up until everything on the page finish loading.

I think Vaadin add-on called LazyLoadWrapper could be just thing you are looking for:
