Review comment:
Late comment: I initially found those double square brackets quite
confusing (why are there double brackets? Is it a list array of one element?)
(I understand this this is because each column is a ChunkedArray (and the
string formatting is coming from there), and so you can have multiple chunks in
the column. So also not necessarily something that can be done about this)
