常用功能加载宏——分行

Excel里有个分列的功能，能根据单元格中指定的符号，把单元格拆分为多个单元格，并按列存放。

有时候会碰上需要按指定的符号，将某些单元格拆分为多行，并且同一行的其他单元格完全复制的情况：

首先在customUI.xml中增加代码：

      <button id="rbbtnSplitRows" label="分行&#13;" size="large" onAction="rbbtnSplitRows" imageMso="CreateDiagram" />

回调函数：

Sub rbbtnSplitRows(control As IRibbonControl)
    Call MRange.SplitRows
End Sub

函数实现：

Private Type SplitDataStruct
    rng As Range '要处理的单元格
    StrSplit As String '要根据什么字符来拆分
    FlagPre As Boolean '是否保持前缀
End Type

Sub SplitRows()
    Dim d As SplitDataStruct
    Dim rngSelect As Range
    
    If VBA.TypeName(Selection) <> "Range" Then
        Exit Sub
    End If
    
    Set rngSelect = Selection
    If rngSelect.Columns.Count > 1 Then
        MsgBox "请选择单列。"
        Exit Sub
    End If
    Dim kCells As Long, i As Long
    kCells = rngSelect.Cells.Count
    
    '这里主要是为了方便自动输入一些经常碰到的要拆分的字符
    Dim strDefault As String
    strDefault = "/"
    Dim strRng As String
    strRng = rngSelect.Cells(1).Value
    If VBA.InStr(strRng, " ") Then
        strDefault = " "
    ElseIf VBA.InStr(strRng, "、") Then
        strDefault = "、"
    End If
    
    d.StrSplit = Application.InputBox("请输入拆分字符。", "输入", strDefault, Type:=2)
    If VBA.Len(d.StrSplit) Then
        If d.StrSplit <> "False" Then
            If VBA.MsgBox("插入时是否保持前缀？" & vbNewLine & vbNewLine & "如ABCDEFG1/2，拆分后是ABCDEFG1和ABCDEFG2，ABCDEFG为前缀", vbYesNo) = vbYes Then
                d.FlagPre = True
            Else
                d.FlagPre = False
            End If
            
            '因为要插入行,所以从最底下的单元格往上处理
            For i = kCells To 1 Step -1
                Set d.rng = rngSelect.Cells(i)
                SplitRngToRows d
            Next
        End If
    End If
    
End Sub

Private Function SplitRngToRows(d As SplitDataStruct) As Long
    Dim strValue As String, strPre As String
    Dim tmp, k As Long, i As Long, flag As Boolean
        
    strValue = VBA.CStr(d.rng.Value)
    If VBA.InStr(strValue, d.StrSplit) Then
        tmp = VBA.Split(strValue, d.StrSplit)
        k = UBound(tmp) '需要插入的行，本身有一行,tmp下标是0,所以要插入的是k行
        d.rng.Offset(1, 0).Resize(k, 1).EntireRow.Insert xlShiftDown
        '其他列的数据都复制保持一致
        d.rng.EntireRow.Copy d.rng.Offset(1, 0).Resize(k, 1).EntireRow
        d.rng.Value = tmp(0)
       
        If d.FlagPre Then
            strPre = VBA.Left$(tmp(0), VBA.Len(tmp(0)) - VBA.Len(tmp(1)))
        End If
        
        For i = 1 To k
            If d.FlagPre Then
                d.rng.Offset(i, 0).Value = strPre & VBA.CStr(tmp(i))
            Else
                d.rng.Offset(i, 0).Value = tmp(i)
            End If
        Next
        
    End If
End Function
