Excel VBA -根据相邻工作表中筛选的行数合并X行中的列

Sub MergeColumns()
    Dim ws As Worksheet
    Dim lastRow As Long
    Dim i As Long
    Dim mergeRange As Range
    
    ' 设置要操作的工作表
    Set ws = ThisWorkbook.Worksheets("Sheet1")
    
    ' 获取最后一行的行号
    lastRow = ws.Cells(ws.Rows.Count, "A").End(xlUp).Row
    
    ' 循环遍历每一行
    For i = 2 To lastRow
        ' 判断是否需要合并列
        If ws.Cells(i, 1).Value = ws.Cells(i - 1, 1).Value Then
            ' 判断是否需要创建合并范围
            If mergeRange Is Nothing Then
                Set mergeRange = ws.Range("A" & i - 1 & ":B" & i)
            Else
                Set mergeRange = Union(mergeRange, ws.Range("A" & i - 1 & ":B" & i))
            End If
        Else
            ' 合并列
            If Not mergeRange Is Nothing Then
                mergeRange.Merge
                Set mergeRange = Nothing
            End If
        End If
    Next i
    
    ' 合并最后一组列
    If Not mergeRange Is Nothing Then
        mergeRange.Merge
    End If
