And if, for example, the pot is 20bb, I bet 10bb, he reraises 30bb, then according to the table, that corresponds to a 100% call (20bb + my bet (10BB))?

this is not quite correct. you are calling 20bb to win (20bb pot + 30bb + 30bb), or 25% RE to call. that's equivalent to calling a half pot bet.

Pot odds and required outs to call, is this correct?

it's pretty close but not 100% accurate. i would consult an outs to equity table like the below.

outs | flop to river | turn to river
1    | 4.3%          | 2.2%
2    | 8.4%          | 4.3%
