comment Friction acting on a particle on a rough place
There is static friction even when the particle is not moving. Friction always acts in the direction to oppose motion.

comment Newton's third law of motion, and the collapse of objects under heavier weight
Newton's third law doesn't say anything about whether the table will collapse. It only says that if the truck exerts a force $W$ on the table, the table also exerts $-W$ on the truck. This is true regardless of whether the truck is in a stationary position.
