column widths not working

[raquelhortab]

Hi! I got a table with subtables inside. I can successfully control the subtables' column widths but not the main table ones.
Here's the code and below the result. If TLDR, important code is towards the end.

tmp_dir = Rails.root.join("tmp")
path = tmp_dir + "work_hours_test.pdf"

pdf = Prawn::Document.new(:page_size => PDF::Core::PageGeometry::SIZES["A4"])

title = [[{content: I18n.t('ubiquo.work_hours_month_validation.pdf.title').upcase, colspan: 3}]]

signature_table = pdf.make_table(
  [
    ["#{I18n.t('ubiquo.work_hours_month_validation.pdf.signature')}:", {image: '/home/raquel/Documents/signature_example.png', :image_height => 70}],
    [{content: "#{I18n.t('ubiquo.work_hours_month_validation.pdf.date')}: #{"???data firma"}", colspan:2}]
  ]
) do |table|
  table.cell_style = {border_width: 0}
end

headers = [
  [{content: pdf.make_table([
                              [
                                pdf.make_table([ [{content: I18n.t('ubiquo.work_hours_month_validation.pdf.company'), colspan: 2}],
                                                 [I18n.t('ubiquo.work_hours_month_validation.pdf.name_or_company_name'), "??"],

month_hours = 0
table_data = work_hours_ranges.group_by(&:date).map do |date, ranges|
  # (some unimportant code ...)

                 table.width = pdf.bounds.width
                 table.column_widths = {1 => 50}
                 table.cell_style = {:background_color => "F1F1F1"}
                 table.row(-1).font_style = :bold
               }, colspan: 3}]]

pdf.table(title + headers + table_data + footer_data) do |table|

  table.header = 4

  # blank separators:
  table.row(2).border_left_width = 0
  table.row(2).border_right_width = 0
  table.row(-2).border_left_width = 0
  table.row(-2).border_right_width = 0

  # title style
  table.row(0).font_style = :bold
  table.row(0).align = :center

  # column headers style:
  table.row(3).font_style = :bold
  table.row(3).font_style = :bold

  # ---> ---> IMPORTANT CODE HERE <--- < ---
  # table.column_widths = {0 => 50, 2 => 50} # I have also tried this way
  table.column(0).width = 50
  table.column(2).width = 50

end

page_numbering_options = {
  at: [pdf.bounds.right - 150, 0],
  width: 150,
  align: :right,
  start_count_at: 1,
}
pdf.number_pages I18n.t('ubiquo.work_hours_month_validation.pdf.page'), page_numbering_options

pdf.render_file path

You can see the footer table respects the widths I've set, but the main content's columns have equal widths.

Thanks in advance!
