Hi everyone,

I'm not sure if this is a bug or if I'm missing something really obvious. But consider these examples:

Dataset works fine here:

Dataset[{Association[
   Rule @@@ Transpose[{CharacterRange["a", "p"], Range[16]}]]}]

The output looks as expected:

However, if I add another column, like this:

Dataset[{Association[
   Rule @@@ Transpose[{CharacterRange["a", "q"], Range[17]}]]}]

... the output looks like this:

I can't see this as expected behaviour, but as I said, maybe I'm missing something and this is a really clever feature... But it certainly looks like a bug! I should add that the example with 17 columns still seems to behave like a Dataset for subsequent operations, but the typesetting/formatting as a tabular structure would really be nice to have as well. Also, this behaviour is not related to the actual width of the output, Dataset works with 16 columns that are much wider than the ones in my example.

For reference, I'm using Mathematica 10.1 in Windows 7.

Thanks for any help you can provide,

Bianca

Edit: Oh, great, found another seemingly related issue: Part with Span also seems to disrupt the formatting:
