IO ANSI Table
Writes data to :stdio in a table with borders and colors.
Can choose a table style to change the look of the table.
Inspired by the book Programming Elixir by Dave Thomas.
Installation
Add io_ansi_table to your list of dependencies in mix.exs:
def deps do
[
{:io_ansi_table, "~> 1.0"}
]
end
You may also define io_ansi_table as an included application, if only using
the IO.ANSI.Table.write/3 function:
def application do
[
included_applications: [:io_ansi_table],
extra_applications: [:logger]
]
endExamples

Table.format(people, style: :light)
Table.format(people, style: :light_alt)
Table.format(people, style: :light_mult)
Table.format(people, style: :cyan_alt)

For side-by-side tables, you can specify a negative top margin.
In addition to the 16 standard ANSI colors<sup>1</sup> and their background counterparts, this package also supports the 256 Xterm colors (foreground and background).
Most of these 256 colors were given names like:
-
<img src="images/00ffff.png">
:aqua -
<img src="images/87ff00.png">
:chartreuse -
<img src="images/d700ff.png">
:psychedelic_purple
For details, see file config/persist_colors.exs of dependency
io_ansi_plus.
