Tabular #
Dart library for easily displaying tabular data in a visually appealing ASCII table format.
Tabular is specifically designed to create tables in the Markdown format that GitHub understands.
The library is inspired by python's tabulate and pretty_table.

var data = [
['Season', '#', 'Name', 'Days', 'Sun'],
['Winter', 1, 'January', 31, 94],
