如何使用RUBY比较CSV中的交替行

require 'csv'

data = CSV.read('file.csv')

alternating_rows = []

data.each_with_index do |row, index|
  next if index % 2 == 0 # 跳过偶数行
  previous_row = data[index - 1]
  alternating_rows << [previous_row, row] if previous_row # 将交替行存储到数组中
end

alternating_rows.each do |rows|
  puts "前一行：#{rows[0]}"
  puts "当前行：#{rows[1]}"
  puts "------------------"
end
