Is it considered a good style to use whitespace to align the code?

For example, what piece of code is considered better styled? If I show my code to a professional developer and ask if my code is good or not, will using the second style be probably considered as a (minor, but...) minus or a plus to my code quality?

I myself tend to like the second style but would prefer to comply to the most common opinion in this case.

1

val foo : Int = -1
val bar : Int = 1
val yohoho : Double = NaN

2

val foo    : Int    = -1
val bar    : Int    =  1
val yohoho : Double =  NaN
