How to set the font size in a shrimp table?

How do I set the font size in a PDF table using the prawn gem?

When I call prawn like the following:

pdf = Prawn::Document.new(:page_size => 'LEGAL', :page_layout => :landscape)
pdf.table data,
    :header => true,
    :column_widths => widths,
    :font_size => 7,
    :row_colors => ["EEEEEE", "FFFFFF"]

I get an NoMethodError

undefined method `font_size=' for #<Prawn::Table:0x6ce37ea4>

When I remove the ":font_size => 7", it renders but I get an undesirable font size.

I am using prawn 0.12.0, ruby 1.9.3p194, and Rails 3.1.9.


You have to apply the size property to the cell text directly. Here is how to do this:

pdf.table data,
  :header => true,
  :column_widths => widths,
  :cell_style => { size: 7 },
  :row_colors => ["EEEEEE", "FFFFFF"]
