Hi Spria!
Which table are you referring to? There are tables available on the VIEW panel that allow you to tab between columns. There are also tables you can add to your reports. These tables do not allow you to change individual values but allow you to specify the channels to display. When you create a user dialog box (SUD) you can also add a table. With this table you can use the arrow keys to move between entries.
I hope this helps!
