Probably related: #189

Hi @astanin, is it possible to fix this issue? We are running into this issue in a third party software in production and would love to see #236 being reviewed and merged.

I think it is related to an issue I just stumbled upon:

tabulate.tabulate([['False'], ['1.']]) will raise a ValueError, my understanding is that it tries to convert the whole column to float, then fails with False. The behaviour I would expect is to not convert anything, I pass strings for a reason, if I want numbers I will pass numbers.
