Net::SMTP.start('localhost') do |smtp|
smtp.send_message message, 'xxx@example.com',
                           recipients
end

上面的代码发送了一封包含如下表格的电子邮件：

Chef  (column1)      |  Check-in Report(column2)   (row 1)

我将数组内容放入要通过电子邮件发送的表格中。我想要第一行第一列中的第一个数组元素，第一行第二列中的第二个数组元素。第二行第一列的第三个数组元素，第二行第二列的第四个数组元素，依此类推。

请尝试这样的事情：

custom_rows = ""
array.each_slice(2) do |row| 
  custom_rows << "<tr><td>#{row[0]}</td><td>#{row[1]}</td></tr>"
end

比在你的messageput里面#{custom_rows}：

message = <<MESSAGE_END
From: xxx@example.com <xxx@example.com>
#{recipients_formatted}
