If I slide a book across the table, will there be friction acting on the table as well?

Answer:
Have you ever tried to get a running start and slide across a smooth, wooden floor while wearing socks? What happens if you try the same thing on a carpeted floor or while wearing shoes? The amount of friction between your feet and the floor surface determines how well you can slide. Some combinations of surfaces, such as socks on a wooden floor, produce very little friction

A friction force exist only when, there is tendancy of relative motion between objects in contect. In a given situation a block is simply kept on the table and the table is in rest so there is no tandancy of relative motion between book and table. hence no friction act.
