TableRex

TableRex is an Elixir library that generates text-based tables for display: in command-line apps, logs, or anywhere else plain text goes. A one-liner renders an ASCII-style table with sane defaults:

TableRex.quick_render!(rows, header, title)
|> IO.puts

Underneath, the table structures support column and cell alignment, titles and headers, sorting on the raw data, colour, padding, multi-line cells, and CJK and Unicode text. Framing and separators can be restyled, GitHub-flavoured Markdown included, and rendering is pluggable for formats the built-in renderer doesn't cover.

It's on Hex with docs on HexDocs, and is listed in Awesome Elixir.
