首先对您的宏稍作改动:
Sub Red_text(r As Range)
Dim i As Integer
Dim MyString As String
MyString = r.Value
For i = 1 To Len(MyString)
If IsNumeric(Mid(MyString, i, 1)) = False Then
r.Characters(i, 1).Font.Color = RGB(247, 66, 66)
End If
Next i
End Sub
并且还在工作表代码区域中包含以下事件宏:
Private Sub Worksheet_Change(ByVal Target As Range)
Dim A As Range
Set A = Range("A:A")
If Intersect(A, Target) Is Nothing Then Exit Sub
Application.EnableEvents = False
Call Red_text(Target)
Application.EnableEvents = True
End Sub
事件宏检测到 A 列的条目,然后应用格式。
编辑#1:
事件宏必须更改为一次处理多个单元格。删除原始事件宏并使用:
Private Sub Worksheet_Change(ByVal Target As Range)
Dim A As Range, rBIG As Range, r As Range
Set A = Range("A:A")
Set rBIG = Intersect(A, Target)
If rBIG Is Nothing Then Exit Sub
Application.EnableEvents = False
For Each r In rBIG
Call Red_text(r)
Next r
Application.EnableEvents = True
End Sub
