Ruby Rails Excel 格式化数组操作

Question

我需要一些关于如何在二维数组中动态定位值的 help/idea。

基本上，我有一个必须满足的条件，它决定了应该将值写入哪一列。

这就是我所拥有的（一个在写入值之前传递条件的循环）：

@records.each do |client|

  client_info  = Report.get_client_info(client)
  client_address = Report.get_client_address(client)

  client_records = []

  client_records << [client_info.id, client_info.full_name]

  if @include_address == "1"
    client_address.each_with_index do |address, i|
      if client_records[i].present?                                    
        client_records[i][2] = address.full_address               
        client_records[i][3] = address.address_type   
      else
        client_records << ["","", address.full_address, address.address_type]
      end             
    end
  end

  if @include_contact == "1"
    client_contact.each_with_index do |contact, i|
      if client_records[i].present?                                    
        client_records[i][4] = contact.value                         
        client_records[i][5] = contact.label
      else
        client_records << ["","","","", contact.value, contact.label]               
      end
    end
  end
end

问题是：如果我想再做一个条件，并且两个（条件）之间的条件不成立，列值的位置设置为：client_records[i][2] >> 2,3 etc ...是硬编码的，而不是第三个条件占据第二个条件列的位置，它自然留空并留在同一个地方。

这是它的样子：

而不是：

我该如何解决这个问题？

例如，尝试这样做：

@records.each do |client|

  client_info  = Report.get_client_info(client)
  client_address = Report.get_client_address(client)

  client_records = []

  line = [client_info.id, client_info.full_name]

  [client_address.count, client_contact.count].max.times do |i|
    if @include_address == "1" && client_address[i]
      line << client_address[i].full_address << client_address[i].address_type
    else
      line << '' << ''
    end

    if @@include_contact == "1" && client_contact[i]
      line << client_contact[i].value << client_contact[i].label
    else
      line << '' << ''
    end

    client_records << line.clone
    line = ['', '']
  end
end
