title: Content duplication Prawn
body: <p>I'm create an where the user can see content online or download it. </p>
  
  <p>I have a nested table which is duplication and I cannot see why.</p>
  
  <pre><code>  def header
      table header_container_table do
        columns(1..2).align = :center
        columns(0..2).border_width = 2
      end
    end
  
    def header_container_table
      contenido_header = [[{image: "#{Rails.root}/app/assets/images/logo.png", scale: 0.6}, header_inner_table_rows]]
    end
  
    def header_inner_table
       inner_content = [["Line 1"], ["Line 2"], ["Line 3"], ["Line 4"]]
    end
  
    def header_inner_table_rows
        table header_inner_table do
          rows(0).size = 18
          columns(0).align = :center
          rows(2..3).size = 8
        end
    end
  </code></pre>
  
  <p>what I'm doing wrong?</p>
