If someone wants to upgrade to the tabular view but does not want to update 'rspec_api_documentation' gem then all they need to do is override the 'section_hash' method for 'JsonIndex' class to include 'route' and 'method' as show below.

  def section_hash(section) 
    {
      :name => section[:resource_name],
      :examples => section[:examples].map { |example|
        {
          :description => example.description,
          :link => "#{example.dirname}/#{example.filename}",
          :groups => example.metadata[:document],
          :route => example.route,
          :method => example.metadata[:method]
        }
      }
    }
  end
