Chair

Me: What's the first thing you think of when I say 'Table'?
J: 'Chair'.

Chair is a simple table implementation for Ruby, with an associated Row class.

Installation

Add this line to your application's Gemfile:

gem 'chair'

And then execute:

$ bundle

Or install it yourself as:

$ gem install chair

>> t = Chair.new :title
=> #<Chair:0x0000000162ee08>

>> t.insert! title: 'Looking for Alaska'
