I tried taking the twist out by clamping one end and pumping the
hydraulic until the table was flat against the pins, but it just
returned after pressure was released.

I think you could put the pin in one end and a single bolt in the low
side of the other and then press it far enough that it springs back
straight. When I do this sort of job I measure how far I pushed the
metal and how far out it still is afterwards. Then next time I can
push it further by the amount of the error.

Say I pressed it 1/2" past alignment and after releasing the pressure
it was still 1/8" short. Next time I'd press it 5/8".
