group_by prevents correct formatting with pandoc

[clayms]

After using group_by, cannot output table with pandoc correctly with the digits= or round= parameters.

Take the group_by out of the chain and pandoc displays the table just fine. Add the group_by in and the number of decimal places of the floating point numbers is way to big to display.

Sven posted a workaround on StackOverflow.
