So long as the height adjustment feet are in the same place as a standard module, it would not be a structural problem for a T-Trak module to extend farther toward the viewer than the edge of the table. At least not until it made it fall off the table from too much weight to counterbalance with what is in the standard locations.
But, if the T-Trak setup is actually going both directions on 30" wide tables, that might indicate a lack of space around it, too, so the front extensions might be "in the isle", so to speak.
