Narrative:

Cleared a PA28 for takeoff on runway 19R at tampa airport with traffic on 3 mile final runway 19R. A B737 was taxiing northbound on taxiway west which is parallel to runway 19R and between runway 19R and taxiway V. The PA28 was on taxiway V and turned down taxiway west with takeoff roll and was airborne within 1;000 ft. The B737 on taxiway west northbound reported that aircraft took off toward him opposite direction then turned west to align himself over runway. I was scanning down runway and as I scanned north saw PA28 airborne and well above the B737 jet. The B737 on 3 mile final reported the PA28 took off taxiway also; as did the PA28; who volunteered the information on frequency. Aircraft rolled and was airborne too quick for me to see or stop the aircraft; and stopping aircraft at that point would have been worse than allowing situation to happen as it did. Being able to line-up-and-wait on the runway without an additional controller in charge person in tower probably would have averted the situation; but we are required to not allow it without more staffing in tower.
