Name
====

`Prettier::Table`, a simple Raku module to make it quick and easy to represent tabular data in visually appealing ASCII tables.

By default it will generate tables using ASCII Box Drawing characters as show in the examples below. But you can also generate [GFM Markdown tables](https://docs.github.com/en/get-started/writing-on-github/working-with-advanced-formatting/organizing-information-with-tables), and MS Word Friendly tables by calling `$my_table.set-style('MARKDOWN')` or `$my_table.set-style('MSWORD-FRIENDLY')` Check out `demo.raku` to see this in action.

This is a fork of [Luis F Uceta's Prettier::Table](https://gitlab.com/uzluisf/raku-pretty-table) which is itself a port of the [Kane Blueriver's PTable library for Python](https://github.com/kxxoling/PTable).

Synopsis
========

**Example 1**:

    use Prettier::Table;

    my $table = Prettier::Table.new:
        title => "Australian Cities",
        field-names => ["City name", "Area", "Population", "Annual Rainfall"],
        sort-by => 'Area',
        align => %('City name' => 'l'),
    ;

    given $table {
        .add-row: ["Adelaide",  1295,  1158259,  600.5 ];
        .add-row: ["Brisbane",  5905,  1857594,  1146.4];
        .add-row: ["Darwin",    112,   120900,   1714.7];
        .add-row: ["Hobart",    1357,  205556,   619.5 ];
        .add-row: ["Sydney",    2058,  4336374,  1214.8];
        .add-row: ["Melbourne", 1566,  3806092,  646.9 ];
        .add-row: ["Perth",     5386,  1554769,  869.4 ];
    }

    say $table;
