Hi guys,
Can we get org-pretty-table into org-mode?
https://github.com/Fuco1/org-pretty-table
It replaces ascii chars with unicode box-drawing characters.
It might be a bit rough around the edges, and Matus himself does not
seem to be currently interested to work on, but it seems to work
satisfying for me.
I would like to have it in org-mode by default as a coplement to
org-pretty-entities and inline images and links.
Attached is the latest source for those who don't like to download
themselves from Github.
I am not sure if I am the best person to work on this; I am not very
well acquainted with org-mode, but I can try to help as much as I can.
