Im using the Prawn gem to generate a pdf table. I need to set the width of the table to 100%. How can I do this?
Here's my slmun_pdf.rb
class SlmunPdf < Prawn::Document
def initialize(slmunDbs, view, allcount)
if slmunDbs.table_name == "schools"
super(top_margin: 50)
if slmunDbs.size != allcount
@warn = " (Not all Schools)"
else
@all = " All #{slmunDbs.size} Schools"
end
text "Showing#{@all}", size: 18, style: :bold, align: :center, color: "636363"
text "#{@warn}", size: 11, align: :center, color: "858585"
@schools = slmunDbs
@view = view
school_list
end
end
def school_list
move_down 20
table school_list_rows, :cell_style => { :font => "Helvetica", :size => 9, :border_width => 0.5, :borders => [:top, :bottom], :border_color => "B0B0B0", :text_color => "737373"} do
self.row(0).align = :center
row(0).background_color = 'A0B046'
row(0).text_color = "FFFFFF"
self.row_colors = ["DDDDDD", "FFFFFF"]
self.header = true
end
end
def school_list_rows
[["Name", "Contact", "Country", "Pre Registration", "Full Registration", "Assigned Countries", "Total Delegates" ]] +
@schools.map do |school|
countries = ""
len = school.countries.count
school.countries.each_with_index do |country, index|
countries << "#{country.country }"
if index+1 != len
countries << ","
end
end
[school.name, school.contact, school.country, @view.yesno(school.prereg), @view.yesno(school.fullreg), countries, school.delegates.size ]
end
end
end
The existing documentations didn't help. I might be using a different method? I learnt this from rails cast!
You can use the width
method of the Prawn::Document::BoundingBox
class:
require 'prawn'
require 'prawn/table'
Prawn::Document.generate("hello.pdf") do
table_content = [["This table"], ["covers the"], ["whole page width"]]
table table_content, width: bounds.width
end
