Undefined method colspan in Prawn

Question

I have correct code, but Prawn complains to it:

class MyClass < Prawn::Document
  # ....
  def def123      
    table main_table , width: bounds.width 
  end

  def main_table
    [[ 
      "0","1", "2", "3", "4"
    ]] + 
    [
      [{content: "data1", colspan: 4}, "111"],
      [{content: "data2", colspan: 4}, "222"],
      [{content:"data3", colspan: 4}, "333"]
    ]
  end
end

by saying:

undefined method  colspan=  for Prawn::Table::Cell::Text:0x007fb86c3e7020

Note that I need to use width: bounds.width to be able to make the table fill a whole page.

I'd recommend updating your Gem file to pull prawn directly from the git repository. Most undefined method errors are the result of using an out of date version:

gem 'prawn', :git => "https://github.com/prawnpdf/prawn.git"
