Ruby Spreadsheet 合併單元格方法

原文出處:http://rubyforge.org/forum/message.php?msg_id=64873

book = Spreadsheet::Workbook.new
sheet = book.create_worksheet :name => "Test Sheet"

bold_heading = Spreadsheet::Format.new(:weight => :bold, :size => 14, :align => :merge)
data = "A TEST HEADING"
test_row = sheet.row(0)

5.times do |i|
test_row.set_format(i,bold_heading)
end

test_row[0] = data

book.write '/Users/sam/tmp/testing.xls'

關鍵點:爲你要合併的所有單元格設置:align => :merge

比如你要合併 a:1 a:2這兩個單元格,那麼這兩個都設置:align => :merge屬性
