height of vaadin table

Hello people,

I am making a vaadin table right now, and i want to set the height and its width by using

setHeight( )

and

setWidth( )

.
I also put a screenshot of my table.

My questions are:
1. how can i make the table so that user can't sort the column and can't modify the width of a column?
2. how can i make the separate line between column longer to the bottom of the table?? (In the forum, we can see that the items are not so much, so there is still a space between the last item and the table bottom line)

Can anyone please help me?
