PagedTable table = new PagedTable("PagedTable Example");

}When you create a new instance of PagedTable then you should create controls layout by using createControls() method. createControls() method returns instance of ControlLayout class. You can do the following then.
ControlsLayout controls = table.createControls();
controls.getItemsPerPageLabel().setValue("Items");
controls.getBtnFirst().setCaption("First");
controls.getBtnLast().setCaption("Last");
controls.getBtnNext().setCaption("Next");
controls.getBtnPrevious().setCaption("Previous");
controls.getPageLabel().setValue("Current:");This is how the paged table is going to look like.
In case you need lazy loading from database you might need this kind of paged table implementation. This is just an example and I don't think usable in real world project. If you want lazy container without much effort try to look here Lazy Container.
