I've tried multiple methods of adding and removing columns to a dataset, but it seems no matter which way I choose I can't get the data to typeset as a table.
Here's my initial dataset:
1) Construct an association using <|#, ... |> syntax (with the Normal form to show that it yields a list of associations):
<|#, ... |>
2) Using Append:
3) Using Join:
In each case, the dataset returns is typeset as a single row. Can anyone shed some light on as to why? I have a hunch that I'm fighting some kind of internal type system. What's strange is given much simpler datasets, each one of these methods works fine.
The problem appears to be an inconsistency in whether to use 1-D or 2-D formatting.
Not exactly a bug, but a change to use 2D formatting when practical is in the works for a future minor release.
