Put simply, TableRex can generate pretty ASCII-like tables for your CLI program or Mix task that look like this:

+----------------+---------------+------+
|     Artist     |     Track     | Year |
+================+===============+======+
|    Konflict    |    Cyanide    | 1999 |
| Marcus Intalex |  Temperance   | 2004 |
| Kryptic Minds  | The Forgotten | 2007 |
+----------------+---------------+------+

The styling is quite customisable; the docs still need more work but you can see the different styles of table you can create by looking at the text renderer tests.
