使用名为 Sheet1 和 Sheet2 的工作表创建一个新工作簿（可以通过更改代码中的常量来更改名称）
添加一个主模块和 3 个 Class 模块（在 VBA 编辑器中单击 Inser > Module 和 Insert Class Module，Alt F11 开始）
将类模块重命名如下：Bill、Item 和 Order
将以下代码添加到Class模块Bill
Option Explicit
Public ID As String
Public ItemName As String
将以下内容添加到类模块项
Option Explicit
Public Name As String
Public ColumnNumber As Long
Private Sub Class_Initialize()
ColumnNumber = 0
End Sub
将以下代码添加到类模块顺序
Option Explicit
Public Bills As Collection
Public ID As String
Public Sub AddBill(BillID As String, ItemName As String)
Dim B As Bill
Set B = New Bill
B.ID = BillID
B.ItemName = ItemName
Bills.Add B
End Sub
Private Sub Class_Initialize()
Set Bills = New Collection
End Sub
将以下代码添加到您的主穆勒

运行例程 process_data（Excel 中的 Alt F8）
此程序不考虑同一订单中具有相同物品（例如咖啡）的多张账单，只会出现一张账单，我不知道您想如何处理这种情况。代码需要检查和错误处理例程以使其对无效数据具有鲁棒性，我添加了一些 cmets 作为提示。
希望对你有帮助
