"Water table" means the level of water underground. So when you dig a well, you have to dig down at least to that level.
Wells get water from the underground water table.
Yes, a drought can cause wells to dry up if the level of the water table falls.
Mostly towns sink wells for drinking water. If they draw off too much water for precipitation, etc. to refill then they cause the water table to fall and the wells will be drilled deeper and the water table will fall more.
If the bottom of a well is above the water table, the well would be dry.
