Table Generator

Plain text table generator for ruby.

Main features:

• Choose column/header alignment (left, center or right)
• CJK characters support
• Embed progress bars (example in the documentation)
• Minimum column length
• Optional size constraint
• Per column data formatter (data is separated from the layout)
• Scale down large tables with collapsible columns
• Scale up small tables with stretchable columns
• Unlimited border length

Add this line to your application's Gemfile:

gem 'tablegen'

And then execute:

$ bundle

Or install it yourself:

$ gem install tablegen

The documentation is hosted at http://rubydoc.info/gems/tablegen/TableGen.

require 'tablegen'

table = TableGen.new
table.header 'Browser Name', 'Layout Engine', 'License'
table.separator
table.row 'Chromium', 'Blink', 'BSD'
table.row 'dwb', 'WebKit', 'GNU GPLv3'
table.row 'Internet Explorer', 'Trident', 'Proprietary'
table.row 'Mozilla Firefox', 'Gecko', 'MPL'
puts table

Output:

Browser Name      Layout Engine License
===========================================
Chromium          Blink         BSD
dwb               WebKit        GNU GPLv3
Internet Explorer Trident       Proprietary
Mozilla Firefox   Gecko         MPL

Set the size constraint and stretch the first column:

table.width = 50
table.column 0 do |col|
  col.stretch = true
end
puts table

Output:

Browser Name             Layout Engine License

Chromium                 Blink         BSD
dwb                      WebKit        GNU GPLv3
Internet Explorer        Trident       Proprietary
