我想通过VBA实现如下的功能：对EXCEL中的Sheet1工作表所有内容复制到新的工作表中，并在G列后插入新的一列，并将Sheet1工作表的G列从第二行开始的数据分别乘上工作表“实时汇率”的A2单元格的数据，将相乘后的数据保存在新生成的工作表的H列

要在Excel中通过VBA实现这样的功能，你需要编写一段宏代码。以下是步骤和VBA代码示例：

首先，在Excel中按下 `Alt + F11` 打开Visual Basic for Applications (VBA) 窗口，然后插入一个新的模块（Module），你可以命名为 "CopyAndMultiply"。

Sub CopyDataMultiply()
    Dim sourceSheet As Worksheet ' Source sheet (Sheet1)
    Dim destSheet As Worksheet ' Destination sheet (new one)
    Dim sourceRange As Range ' Range to copy from Sheet1
    Dim newRow As Long ' Index for the new row in the destination sheet
    Dim sourceCell As Range ' Cell iterator in G column
    Dim rateCell As Range ' Cell containing the exchange rate
    
    Set sourceSheet = ThisWorkbook.Sheets("Sheet1")
    Set destSheet = ThisWorkbook.Sheets.Add(After:=sourceSheet) ' Create a new sheet after Sheet1
    newRow = 2 ' Start at row 2 since you want to multiply starting from the second row
    
    ' Copy all data from Sheet1's A1:G1000 to the destination sheet, inserting a new H column
    With destSheet
        .Name = "Sheet1_copy" ' Rename the destination sheet (optional)
        Set sourceRange = sourceSheet.Range("A1:G1000") ' Adjust this range if needed
        sourceRange.Copy .Cells(1, 1) ' Paste to top-left cell
        
        ' Insert a new H column and set its width
        .Columns("H").Insert Shift:=xlToLeft
        .Range("H1").AutoFit
    End With
    
    ' Multiply values in Sheet1's G column by the exchange rate
    Set rateCell = Worksheets("实时汇率").Range("A2") ' Adjust the sheet name and cell reference as needed
    For Each sourceCell In sourceSheet.Range("G2":G1000) ' Loop through cells from G2 to the last row
        If Not IsEmpty(sourceCell.Value) Then ' Skip empty cells
            .Range("H" & newRow).Value = sourceCell.Value * rateCell.Value
        End If
        newRow = newRow + 1
    Next sourceCell
End Sub

记得替换代码中的 "Sheet1", "实时汇率", "A2", 和范围限制 ("A1:G1000") 为实际的工作表名、需要使用的单元格以及你要处理的实际数据范围。
