I have a similar (hydraulic) lifting table, it is worth its (substantial) weight in gold. Got it from eBay, it wasn't expensive although I did have to drive to South Wales to collect it.
I bought a sheet of plywood to sit on the table top, sometimes being able to slip the bike about when it is on it's stand has been useful. I drilled the table top for U bolts, then used some suitably sized exhaust clamps from Halfords.
I also have a small scissor jack - it was the one supplied with the toolkit on my Bedford HA (Viva) van long long time ago. The front wheel clamp is useless, if it is a 'cost option' - don't bother.
I have the table placed in the centre of the garage floor, one bike is permananently parked on the table, so no loss of floor space.
Parking a bike on it's centre stand on the centre line of the table can be a bit of a struggle, the T140 is easy, but the Scrambler can be less easy, you will need to stand / balance on the edge of the table while you lift the bike over the stand.
