自定义excel公式函数UDF来计算条件格式

Question

有没有人遇到过一个真正适用于条件格式的函数？

kutools 和 albebits 有一些插件，但它们不是基于公式的（您必须手动选择所有内容）

我找到了这个，但仅适用于手动格式化

Function ColorFunction(rColor As Range, rRange As Range, Optional SUM As Boolean)
Dim rCell As Range
Dim lCol As Long
Dim vResult
lCol = rColor.Interior.ColorIndex
If SUM = True Then
   For Each rCell In rRange
    If rCell.Interior.ColorIndex = lCol Then
            vResult = WorksheetFunction.SUM(rCell) + vResult
    End If
   Next rCell
Else
    For Each rCell In rRange
    If rCell.Interior.ColorIndex = lCol Then
            vResult = 1 + vResult
    End If
   Next rCell
End If
ColorFunction = vResult
End Function

继@Jeeped 和@Comintern...

这对我有用 - 一个简化的例子：

Function WrapCountReds(rRange)
    WrapCountReds = rRange.Parent.Evaluate("CountReds(" & _
                          rRange.Address(False, False) & ")")
End Function

'can't call this directly from a worksheet but can be called via evaluate
Public Function CountReds(rRange As Range)

    Dim rCell As Range
    Dim vResult

    For Each rCell In rRange
      If rCell.DisplayFormat.Interior.ColorIndex = 3 Then
             vResult = 1 + vResult
      End If
    Next rCell

    CountReds = vResult
End Function

工作表使用示例：

=WrapCountReds("A1:A100")
