To use Tabled in your application, follow these steps:

1. Require the gem in your code:

   require 'tabled'

2. Pass an array of rows to the application. Each row can contain any number of columns and optional footer text.

Tabled accepts the following options:

• framed (optional, default: true): Specify if the output should have frames.
• row_separator (optional, default: "-"): Set the character for row separators or set it to nil if you don't want to separate rows.
• titles (optional): Provide a list of column titles.

Here are some examples to help you get started:

data = [
  ["Helena", "20 years", "Female"],
  ["John", "18 years", "Male"],
  ["Alan", "23 years", "Male"],
]

Tabled.new(data, framed: false, row_separator: nil).print_to_console

Helena 20 years Female
John   18 years Male
Alan   23 years Male

data = [
  ["Helena", "20 years", "Female"],
  ["John", "18 years", "Male", { footer: "Legendary assassin John Wick (Keanu Reeves)." }],
  ["Alan", "23 years", "Male"],
]

Tabled.new(data, row_separator: nil).print_to_console

| Helena 20 years Female                       |
| John   18 years Male                         |
| Legendary assassin John Wick (Keanu Reeves). |
| Alan   23 years Male                         |

csv = CSV.parse(<<~ROWS, headers: true)
  Bob,Engineering,1000
  Jane,Sales,2000
  John,Management,5000
ROWS

Tabled.from_csv(csv: csv, framed: true).print_to_console

| Bob  Engineering 1000 |
-------------------------
| Jane Sales       2000 |
-------------------------
| John Management  5000 |
-------------------------

You can export the data in CSV or JSON formats. By default, the file is saved in the current directory with the file name "tabled.csv" (CSV format).

# Export to CSV
Tabled.new(data).export_to_file

# Export to JSON
Tabled.new(data, titles: ['Name', 'Age', 'Gender']).export_to_file(format: :json)

# Customize file name
Tabled.new(data, titles: ['Name', 'Age', 'Gender']).export_to_file(file_name: 'my_file.json')

As part of the gem, the tabled binary is included. You can run it like this:

tabled print path_to_[csv|json]_file
