I know this had to do with inertia, but I need to explain what this is demonstrating and can't figure out how to word it.

If you pull the cloth fact enough it doesn't exert force on the settings and therefore the settings remain at rest.

It has to do with friction. If you were to try this with a sheet of rubber, there would be dishes everywhere. But, when done with smooth cloth, the acceleration of the table cloth is too great for the smooth dishes to grab the smooth cloth. It's the same concept as accelerating your car on ice. If you punch the gas, the tires will spin on the ice. But if you accelerate slowly, the tires will grab the surface and move you forward.
In a nutshell, the acceleration of the cloth is greater than the friction between the dishes and the cloth. Thus, the dishes slide atop the table, and the tablecloth is pulled out.

static friction is overcome.
friction only works up until a certain point as you can tell from when a car skids out of control. Beyond a certain force, static can no longer hold the object in place. Same is with the tablecloth, it moves with a greater force than that required to hold the items in place.
I have no idea if this is true, but it makes sense.

Friction being slight there is not much force on the table setting. Since the forces are slight the portion of Newtons law that says objects will stay still unless acted upon by an external force.

Newton's first law of motion is demonstrated.
