Review Comment:
Sorry, should column_names also be named columnNames (I understand that this
was before this PR). I'd also suggest fixing the names of other variables in
this method.

Review Comment:
Any chance we can handle these more cleanly? Like adding a function to
handle lists or append null if empty that takes in a lambda? (Not a Go expert).
If this were C# you could do an extension method on the builder but not sure
if the concept exists in Go (or perhaps just a new instance method on the
builder...).
