QR Codes are not within the table cells

[Jefferson Francisco]

I need to place a qr code within the first column of a table for each row. The QR code contains the ID for each organization

I am using the following gems

gem 'prawn'
gem 'prawn-table'
gem 'prawn-qrcode'

Here is my code (I will attach a screenshot below to show my result):

require 'prawn/qrcode'

class ReportPdf < Prawn::Document

  def initialize(organizations)
    super()
    @organizations = organizations
    header
    text_content
    table_content
  end

  def header
    image "#{Rails.root}/app/assets/images/logo.png", width: 530, height: 150
  end

  def text_content
    y_position = cursor - 50

    bounding_box([0, y_position], :width => 270, :height => 300) do
      text "Organizaciones", size: 15, style: :bold
      text "Lorem ipsum dolor sit amet, consectetur adipiscing elit."
    end

    bounding_box([300, y_position], :width => 270, :height => 300) do
      text "Duis vel", size: 15, style: :bold
      text "Duis vel tortor elementum, ultrices tortor vel, accumsan dui."
    end
  end


  def table_content
    table organization_rows do
      row(0).font_style = :bold
      self.header = true
      self.row_colors = ['DDDDDD', 'FFFFFF']
      self.column_widths = [40, 300, 200]
    end
  end

  def organization_rows
    [['#', 'Name', 'id']] +
      @organizations.map do |organization|
        [render_qr_code(RQRCode::QRCode.new(organization.id.to_s, :size => 2)).to_s,
          organization.name,
          organization.id]
      end
  end

end

Here is the outcome:
