prawn-table question.

[Hiroyuki Sato]

Hello

I have a question about prawn-table (0.2.1)

* Is it possible to create new page automatically if content(one-table) does not fit single page?

* How do I know table height like dry_run in TextBox?

Please see detail.

Thank you for your advice.

I guess a box has a height method?

Hello rogerdpack.

I can calculate like this 

table.row_heights.inject(0){ |sum,h| sum += h }

Thanks.

Hello Aditya

This is example code. 

Please check this URL.

https://gist.github.com/hiroyuki-sato/8fbe9516c6c74e189f6a

Please let me know if you need more detail.

table = Prawn::Table.new(data,@pdf,table_opts) do

...

end

if( fits_on_current_page?(table) == false )

  @pdf.start_new_page

end

UNDER_MARGIN = 5.mm + 10.mm

# 

def fits_on_current_page?(table)

  h = table_height(table)

  #@pdf.y is current height position.

  @pdf.y - UNDER_MARGIN > h

end

# calculate table height.

def table_height(table)

  table.row_heights.inject(0){ |sum,h| sum += h }

end

Thanks

Hiroyuki Sato.

HI Hiroyuki,

Thanks to answer.

But i am quite new for rails programming.

I am using prawn-table gem to create table

file_location = file_path + "/" + file_name + ".pdf"

    pdf = Prawn::Document.new(:template => file_location, :skip_page_creation => true) do

    start_new_page(:template => file_path)

    end

#data is 2D array

    pdf.indent(10) do

      pdf.table(data, :header => true ) do

        rows(0..data.length).style(:border_width => 1, :align => :center).size=12

        row(0).style(:background_color => '01d4ab', :border_width => 1,:align => :center, :font_style => :bold, :text_color =>'000000')

        if change_config != nil

          change_config.each do |c|

            row(c).style(:background_color => 'FFFF00', :border_width => 1,:align => :center, :font_style => :bold)

          end

        end

      end

      pdf.number_pages "Page <page> of <total>", :at => [432, -4], :width => 100,  :text_color =>'00ff00'

      pdf.render_file  file_location

    end

I want to fit that code .please suggest.

Thanks,

Aditya

Hello Aditya.

Could you tell me more detail what is the problem?

I modified your code. It seems work well.

Very nice to modified the code as working. :)

I just gave you piece of code from my program.

Okay. well now what is my problem:

actually that data 2D array contains n number of row like and one of the row contains microsoft security patch id's (KB's).

Some time we have more than 500 kb ids in that one row . so, in my code when size exceed from A4 paper size it will skip rest data what not fit in one page.

I want to achieve like what left in a row should print in next page.

Hope now you can understand my problem.

Hello Aditya

I've never tried that data.

Have you ever tried table/basic_block.rb?
