A scanning table includes an upper pallet, a lower pallet, a support device, a driving device, an opening belt and an endless belt. The opening belt is fixedly coupled with the lower pallet. The endless belt is fixedly coupled with the upper pallet. A front end of the opening belt is provided with a first driving wheel coupled to the driving device. The lower pallet is driven by the first driving wheel to move in a front-back direction relative to the support device. The endless belt is sleeved on the lower pallet. When the lower pallet moves in the front-back direction relative to the support device, the endless belt moves synchronously with the lower pallet to drive the upper pallet to move in the same direction back and forth relative to the lower pallet.
