#143 Tables
Generating data tables in the console from Array, Hash, or ActiveRecord objects with the tablesmith gem.
Notes
I learned of the tablesmith gem in rubyweekly #492.
It’s a pretty neat little utility for generating console tables.
Taking it for a quick test drive…
Running the Example
The Gemfile specifies the gem requirements. bundle install as usual.
$ gem install bundler && bundle install
$ ./example.rb
