you can use Alias map (see Tools~Alias Map) to define that this sort of GUIObject is a button, editbox or something, but I do not expect that this can be done in your case. If TP does not identify the two tables as seperate objects this means that there is an upper container object that does not let TP identify its child objects. Or the tables are no objects at all, maybe its just a couple of lines and text that is painted by the application on a drawing area.
First, attach to the GUIObject. Then you can try
See menu view~Immediate if it prints anything to the immediate window. You can use
to select a specific text that appears in the table and therefore also check if the value is there...
