SOURCE: The X-Values in the Table
What are you trying to do? You drew a graph, then you cleared the function graphed and went to the table to see if the X values have disappeared and they did not.Right?
By pressing the [SHIFT][(TABLE) key you were in fact commanding the calculator to generate a table for a function but you did not supply (nothing in Y= editor), and the calculator faithfully obeyed you. It looked at the Xmin of the window, looked at the Xscl factor and generated a blank table that contains all the X-Coordinates (where your function or table would have been calculated had you entered a valid expression in the Y= editor). That is how it works.
