Library pretty print values in Tabular format
Hello All, I am happy to publish a new library on Hackage that lets one print values contained in lists, maps, vectors in a tabular format. This is motivated from the output I am used to seeing while using the Pandas library in Python. This is my first Haskell library and I look forward to feedback and suggestions on improving the library. https://hackage.haskell.org/package/pptable https://github.com/gdevanla/pptable#readme One thing, which I right away do not like about the library is the constraints where the values will have to derive from both Data.Data and GHC.Generic.Generics. Thank you and I look forward to some feedback. Regards Guru P.S: I spent a lot of time trying to make Hackage produce the haddock links. Any pointers to that would be helpful. And "stack sdist" does not package the documentation automatically.
I like it! One feature I would like to see: Have you considered aligning decimal points? I.e. an output along the lines of ticker price marketCap "YHOO" 42.2910101 0.40 e11 "GOOG" 774.210101 5.3209 e11 "AMZN" 799.161717 3.7886 e11 or something like that. In this format, it is easier to survey the order of magnitude of a quantity. Then again, exponents `e10` may be trickier to handle.

Would it be possible to go polymorphic on the container shape? Eg Rather
than having toBoxVector etc, create a Traversable a => Boxable a class with
a toBox method etc.
If you go aligning decimals, the Formatting library would come in handy.

Thanks for the feedback.
@Heinrich Yes, that would be nice. I was hoping in the future, I could
allow for the user to set some kind of precision value. That would make
sure we have a fixed number of digits after the decimal. May be for now, I
could "fix" that value and make it align.
@Tony Yes, I do have a piece of code commented out where I attempted to
make it generic but did not pursue that option. Your suggestion is very
valid and I am hoping to get there.
