if you want to do T-Bar rows to hit your upper back (rhomboids, teres major, upper lats, traps, rear delts) you can recreate the movement by doing a wide grip cable row with a lat pulldown bar to your lower-to-mid chest region, or you could do a bent over row in the smith machine to the same area.
The way to create the T-Bar row as has been suggested is in fact quite good, but this movement can also be recreated with Bent Over Dumbbell Rows.
