That is a mistake. The appearance of a table on the base is the object to be refuted by the Prasangikas. For the Svatantrikas, it is slightly different. But the Prasangikas say that even a merely labeled table cannot be found on the base. Through your own analysis and meditation you will come to this conclusion.
All phenomena exist by being merely labeled by mind and are empty of existing from their own side.
What blocks us to see this is that we can't differentiate the base and the label. In our perception these two are mixed. Kyabje Ling Rinpoche defines the object to be refuted as the appearance of the phenomenon with the base and the label being undifferentiatable. His Holiness the Dalai Lama defines it as the label of the phenomenon being mixed in the base, inside the base. If you think you see a merely labeled table on the base, it means you see the appearance of an inherently existent table.
