Research direction
No file or test is named. Start by locating the data.table code that formats column type labels and check existing tests for display output. Done means double columns are labeled "dbl" rather than "num", while integer and double columns remain distinguishable.
Written by the indexing model from the issue text.
Description
Since both doubles and integers are numeric. It is confusing to label a data.table column of doubles as "num". In tibble, such a column is labelled as "dbl", which is more accurate.
> is.numeric(1)
[1] TRUE
> is.numeric(1L)
[1] TRUE
