ruby-on-rails - 表格单元格边框

Question

这是我需要生成的 2x2 表：

r1c1  r1c2
r2c1  r2c1
      ----

换句话说，我应该打印右下角单元格的底部边框。这是我的代码：

显示.pdf.虾

#This is a two dimensional array:
my_array = [["r1c1","r1c2"],["r2c1",Prawn::Table::Cell.new(:text => "r2c2", :border_width => 1 , :borders => :bottom)]]

#Table
pdf.table my_array, :border_width => 0

好吧，有了这段代码，我就有了一个没有边框的 2x2 表格！

有人有小费吗？

Answer 1

这里有一个更好地称为解决方法的解决方案：

#This is a two dimensional array:
my_array = [["r1c1","r1c2"],["r2c1",Prawn::Table::Cell.new(:text => "r2c2", :border_width => 1 , :borders => [:bottom])]]

#Table
pdf.table my_array, 
#:headers => ["h1","h2"],
:border_style => :underline_header

省略标题 => ["h1","h2"]可以避免带下划线的标题。
