I'm making a little script with ruby which produces a week schedule PDF file, using Prawn as a PDF library and I'm struggling with styling the table. I'd like to set a static width for all the columns in the table so that the widths wouldn't depend on the contents of the cells.
I've read the documentation (lot of room for improvement there) from the Prawn project site and googled for a few hours, but I'm lost at how to set width for columns or cells in a table, or how to style the columns/cells in any way whatsoever. I do get a PDF file which has a grid layout though, the cells just vary in size a lot, which doesn't look that neat.
This didn't work:
Prawn::Document.generate(@filename, :page_size => 'A4', :page_layout => :landscape) do
table(course_matrix, :headers => HEADERS, :border_style => :grid, :row_colors => ['dddddd', 'eeeeee'], :column_widths => 50)
end
Here's the current version of my method to generate PDF, but it doesn't stylize the cells either:
def produce_pdf
course_matrix = DataParser.new.parse_for_pdf
Prawn::Document.generate(@filename, :page_size => 'A4', :page_layout => :landscape) do
table(course_matrix, :headers => HEADERS, :border_style => :grid, :row_colors => ['dddddd', 'eeeeee']) do |table|
table.cells.style { |cell| cell.width = 50 }
end
end
end
I do something like this:
pdf = Prawn::Document.new(
:page_size => 'A4',
:page_layout => :landscape,
:margin => [5.mm])
....
....
pdf.table(tbl_data) do
row(0).style(:background_color => 'dddddd', :size => 9, :align => :center, :font_style => :bold)
column(0).style(:background_color => 'dddddd', :size => 9, :padding_top => 20.mm, :font_style => :bold)
row(1).column(1..7).style(:size => 8, :padding => 3)
cells[0,0].background_color = 'ffffff'
row(0).height = 8.mm
row(1..3).height = 45.mm
column(0).width = 28.mm
column(1..7).width = 35.mm
row(1..3).column(6..7).borders = [:left, :right]
row(3).column(6..7).borders = [:left, :right, :bottom]
....
pdf.render()
