By default, if you are in Layout or in Sketch tab, tables are not selectable.
It’s not necessary to look in what tab you are . Just move the mouse over the table. If the table do not pre-highlight, press (and hold) the Alt key. Now, with the Alt key pressed, the table can be selected (and then moved).
Maybe you have disabled preselection highlighting?
