In my opinion, both are good ways to express the same thing.
The second one is more expressive; but we all can store a 3-lines
snippet of code in our short-term memory.

The interesting question here is: is table2 a possibly long list?
If yes, then can we convert it to a set, without impairing the
clarity of the code?
