简述：

其实很简单的操作，就是两次筛选后复制Item1全部数据到Item2中，两个Item有且只有一行。

草稿1

打开工作表：通过工作表名称来定位和激活工作表。
定位筛选判断列：在第一行中找到Product的列，然后进行筛选。
筛选指定名称：首先筛选出包含 name1 "Apple"和name2"Banana"的行。
**再次筛选Country **：在筛选出的结果中，基于Country （US、HK、CN）进行进一步筛选并复制数据。

    Dim ws As Worksheet
    Dim filterColumn As Long
    Dim lastRow As Long
    Dim i As Long
    
    ' 尝试访问工作表
    On Error Resume Next
    Set ws = ThisWorkbook.Worksheets(sheetName)
    On Error GoTo 0
    
    If ws Is Nothing Then
        MsgBox "工作表 '" & sheetName & "' 不存在。", vbExclamation
        Exit Function
    End If
    
    ' 找到筛选判断列
    filterColumn = 0
    For i = 1 To ws.Cells(1, ws.Columns.Count).End(xlToLeft).Column
        If ws.Cells(1, i).Value = columnName Then
            filterColumn = i
            Exit For

    ' 清除现有筛选
    If ws.AutoFilterMode Then ws.AutoFilterMode = False
    
    ' 应用筛选
    ws.Range("A1").AutoFilter Field:=filterColumn, Criteria1:=name1
    ws.Range("A1").AutoFilter Field:=filterColumn, Criteria2:=name2
    
    ' 复制数据
    lastRow = ws.Cells(ws.Rows.Count, filterColumn).End(xlUp).Row

                ' 找到产地并复制数据
                Select Case ws.Cells(i, "A").Value
                    Case "US", "HK", "CN"
                        ' 复制C列以后的数据到Banana对应行
                        ws.Cells(i, "C").Resize(1, ws.Columns.Count - 3).Copy
                        For j = 2 To lastRow
                            If ws.Cells(j, filterColumn).Value = name2 And ws.Cells(j, "A").Value = ws.Cells(i, "A").Value Then
                                ws.Cells(j, "C").PasteSpecial Paste:=xlPasteValues
                            End If
                        Next j
                End Select
            End If
        End If
    Next i
    
    ' 关闭筛选
    If ws.AutoFilterMode Then ws.AutoFilterMode = False
    
    MsgBox "数据复制完成。"
End Function

草稿2

接受工作表名称、列名称、以及两个筛选值作为参数。
在指定的工作表上执行筛选操作。
对筛选后的数据，按国家分类，将指定类别（Apple）的数值复制到另一个类别（Banana）中。
