You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: data_table_iruby.rb
    path of file: ./repos/daru-view/lib/daru/view/adapters/googlecharts
    
    the code of the file until where you have to start completion: require 'securerandom'
require 
    
    def initialize(options={})
      @cols = []
      @rows = []
      @listeners = []
      @options = options
      return if options.empty?

      new_columns(options[:cols]) unless options[:cols].nil?

      return if options[:rows].nil?

      rows = options[:rows]
      rows.each do |row|
        add_row(row[:c])
      end
    end
