>我有一个继承虾的 ExportPdf 类 :: 像这样的文档 -
class ExportPdf < Prawn::Document
def initialize(vehicles, view, page, *args)
super({:top_margin => 70, :page_size => 'A1'})
@view = view
@page = page
file_heading
table_data
end
def table_data
move_down 30
table table_data_rows do
row(0).font_style = :bold
self.row_colors = ["DDDDDD", "FFFFFF"]
self.header = true
end
But I have atleast 20 table columns and the only way to accommodate is by increasing page size as,
:page_size => 'A1'.
但这将使它无法打印,因为以 A4 布局打印将不再可能。如何减小字体大小或其他内容以容纳所有 20 个表格列并能够以 A4 布局打印它?
您可能可以使用/添加cell_style
例:
:cell_style => { :size => 10,:border_color => "FFFFFF",:text_color => "333333", :padding => 0, :inline_format => true}
更改大小值以更改表格文本的字体大小。
