我有一些我经常使用的代码(它甚至还有一个用户界面)。它为 ActiveSheet 的第 1 行中包含内容的每个单元格创建动态命名范围。它将“rng”添加到单元格的内容中以形成名称,并检查非法字符。这些和空格被替换为下划线:
Sub AddDynamicNamedRanges()
Dim ws As Excel.Worksheet
Dim rngColumns As Excel.Range
Dim LastCol As Long
Dim cell As Excel.Range
Dim Prefix As String
Dim IllegalCharReplacement As String
Dim RangeName As String
Set ws = ActiveSheet
Prefix = "rng"
IllegalCharReplacement = "_"
With ws
LastCol = .Cells(1, Columns.Count).End(xlToLeft).Column
Set rngColumns = .Range(.Cells(1, 1), .Cells(1, LastCol))
For Each cell In rngColumns
If Not IsEmpty(cell) Then
RangeName = GetCleanedName(Prefix & cell.Text, IllegalCharReplacement, True)
.Names.Add Name:=RangeName, RefersTo:= _
"=Index(" & cell.EntireColumn.Address & "," & 2 & "):Index(" & cell.EntireColumn.Address & ",Max(" & 2 & ",COUNTA(" & cell.EntireColumn.Address & ")))"
End If
Next cell
End With
End Sub
Function GetCleanedName(ObjectName As String, Optional CharReplacement As String = "_", Optional Truncate As Boolean = True) As String
Dim NewName As String
Dim IllegalChars As String
Dim MaxLength As Long
'the "\" character escapes the Regex "reserved" characters
'x22 is double-quote
IllegalChars = "\||\^|\\|\x22|\(|\)|\[|]|\$|{|}|\-|/|`|~|!|@|#|%|&|=|;|:|<|>| "
'255 is the length limit for a legal name
MaxLength = 255
NewName = Regex_Replace(ObjectName, IllegalChars, CharReplacement, False)
If Truncate Then
NewName = Left(NewName, MaxLength)
End If
GetCleanedName = NewName
End Function
Function Regex_Replace(strOriginal As String, strPattern As String, strReplacement, varIgnoreCase As Boolean) As String
' Function matches pattern, returns true or false
' varIgnoreCase must be TRUE (match is case insensitive) or FALSE (match is case sensitive)
' Use this string to replace double-quoted substrings - """[^""\r\n]*"""
Dim objRegExp As Object
Set objRegExp = CreateObject("Vbscript.Regexp")
With objRegExp
.Pattern = strPattern
.IgnoreCase = varIgnoreCase
.Global = True
End With
Regex_Replace = objRegExp.Replace(strOriginal, strReplacement)
Set objRegExp = Nothing
End Function
