I have a file named report.pdf.prawn, which is the view part of my PDF file where we can edit the contents of the PDF file like >>> pdf=Prawn::Document.new(:page_layout =>:landscape,:page_size => 'A4') pdf.text"Hello"

head=@headers headers=[""],[""] pdf.table headers, :width => 768, :size => 11, :border_style => :underline_header, :headers => [head.titleize], :header_color => 'b7e3fe', :padding=>5

<<< etc ect... The above just prints like

Hello Header1header2header3

I have two values from my controller >>> def report <<< as @header and @data

@header gives values like>> Header1Header2Header3 @data gives values like>> data11data12data13data21data22data23

How do i print the values like the format given below on all PDF pages being generated?

Header1 Header2 Header3

data11 data12 data13 data21 data22 data23 data31 data32 data33 data41 data42 data33

Please help.

Hi,

Use the :column_widths=>{0=>100,1=>100, 2=>100, etc..} property.

I used the " :column_widths " property before, since the Header field comes in as hash values, te :column_widths of 0=>100 will be assigned to the first header only, the remaining cell widths will not be taken.

What i was asking, is the format to be printed on PDF. thanks for replying.

headerbar=   @data.each do |column|      data=

     if @headers.include?('dataXX')      column.number      data << column.number      end

                 if @headers.include?('dataXX')      column.number      data << column.number      end

headerbar << data

end pdf.table headerbar, :width => 768, :size => 11, :border_style => :underline_header, :headers => @header, :header_color => 'b7e3fe', :column_widths=>{0=>55,1=>100,2=>70,3=>77,4=>88,5=>90,6=>75,7=>75,8=>75,9=>65,10=>55,11=>55}, :padding=>5

Not fully rectified, but works.
