[NTG-context] Vertical space after "tabulate"

Hello, just a brief question - - is it possible to affect the vertical space after [\starttabulate ...] \stoptabulate? In the example attached, the space after each "tabulate" is too wide. I'd like to achieve space closer to "normal spacing", i.e. distance between "B" and "a" (and between "b" and "U") "equal as much as possible" to that between "U" and "V". Is it possible somehow? Best regards, Lukas
