If a book is in contact with the table, then the book exerts a contact force on the table, but the table doesn;t move, is this because the resultant force on the table is 0 ? What are the forces acting on the table ? It's weight, contact force with the table and contact force with the ground ? Is there anything else ? Is the contact force from the ground enough to equalize the other 2 forces ?

Or does the table not move because the force exerted on it by the book is too small and the mass is too big to create a visible effect ?

Ok well this depends also on the table surface if it is smooth or rough to check the presence of friction.
And yes the summation of forces is zero so equilibrium is attained..the only force acting on the table is the weight (neglect friction) and table as a support has the normal reaction so that W=N.R
