Ruby大虾-table gem：如何select最后一行table？

Question

我有一只大虾table如下：

table info_rows do
  row(0).font_style = :bold
  row(0).align = :center
  row(0).borders = [:top, :bottom, :left, :right]
  row(1..50).borders = [:left, :right]
  self.header = true
  self.row_colors = ['EEEEEE', 'FFFFFF']
  self.column_widths = col_sizes
end

我需要在最后一行放置一个底部边框，但我不确定如何检测循环中的最后一行？类似的东西（循环内的以下 if 语句显然不起作用/只是示例）...

table info_rows do
  row(0).font_style = :bold
  row(0).align = :center
  row(0).borders = [:top, :bottom, :left, :right]
  row(1..50).borders = [:left, :right]

  if row.last
    ?(?).borders = [:bottom, :left, :right]
  end

  self.header = true
  self.row_colors = ['EEEEEE', 'FFFFFF']
  self.column_widths = col_sizes
end

欢迎提出任何想法。

我正在使用 Ruby - 2.1.2

你可以试试这个：

table info_rows do
  row(0).font_style = :bold
  row(0).align = :center
  row(0).borders = [:top, :bottom, :left, :right]
  row(1..50).borders = [:left, :right]
  row(-1).borders = [:bottom, :left, :right]

  self.header = true
  self.row_colors = ['EEEEEE', 'FFFFFF']
  self.column_widths = col_sizes
end
