Wrap the table top in packing paper. Secure the paper with tape to ensure that it doesn't work itself loose and expose a part of the table during the moving process.
Make a cardboard container for the table top. If you are using a professional moving company, they may provide you with a cardboard container. If you are moving your furniture yourself, then make your own container. Measure the table and find a couple of boxes that fit the table's dimensions. Cut the sides of the boxes to make a front and back side for the cardboard container.
Place the tabletop inside of the cardboard container. Secure the container with tape to prevent it from coming open.
Carefully pack the table top. Write packing instructions on the cardboard such as "Fragile" and "Handle with Care." If you are using professional movers, tell them about the contents of the box. If you are moving the table top yourself, place the table top inside the truck so that it is flat against one side. Tie the top with rope to prevent it from shifting or moving. Protect the table top by placing a mattress and box springs next to it.
