If you want each row to hold _different_ cumulative probabilities drawn at
random from something, but broadly following your chosen non-random pattern, it
sounds like you will need to decide what joint distribution you want to draw
those probabilities from so that the cumulative 'probability' is strictly
monotonic. You might then be able to work out how to map the multivariate [0,1]
output of randomLHS to generate the relevant points. It's possible that a
simple kludge applied row-wise to [0,1] values might work, but a) I can't think
of one quickly and b) I'd have a hard time defending it if I did.
It sounds like you need to find a nearby statistician and explain what you are
trying to achieve. They should be able to tell you either how to get there or,
perhaps, why it's not sensible to start and what to do instead.
Sorry I can't help further
