如果值是某个数字，则使用 E​​xcel-VBA 为范围 y 着色，如果值是某个数字，则颜色范围 x 被放置

Question

我需要在 Excel VBA (2016) 中编写条件格式，而不使用现有的条件格式工具。由于我是新手并且尝试了一段时间以下，我请求你帮助我。

我想写这个，例如在私有子中：对于 E18:G18 和 K1:K10 范围：

如果值 >=1，则颜色 = 绿色

如果值为

对于范围 B1:B10

如果值 >=3，则颜色 = 绿色

如果值为 0，则颜色为黄色

如果值为 0 或 "" 红色

我的代码如下 - 当我保存它时，在我的第二个定义范围 (K1:K10) 内没有任何反应，在重新打开 excel 工作簿之后也是如此。

我的第二个条件格式范围 (B1:B10) 也没有任何反应：

Private Sub Worksheet_Change(ByVal Target As Range)

Dim rngObserve As Range, rngCell As Range

Set rngObserve = Intersect(Target, Range("E18:G18, K1:K10"))

If rngObserve Is Nothing Then
    Exit Sub
End If
For Each rngCell In rngObserve.Cells
    If Not Intersect(rngCell, rngObserve) Is Nothing Then
        If rngCell.Value = vbNullString Then
            rngCell.Interior.Color = xlNone
        ElseIf rngCell.Value < 1 Then
            rngCell.Interior.ColorIndex = 3 'red
        ElseIf rngCell.Value >= 1 Then
            rngCell.Interior.ColorIndex = 4 'green
        Else
            rngCell.Interior.ColorIndex = 3 'red
        End If
    End If
Next



Dim rngObserve As Range, rngCell As Range

Set rngObserve = Intersect(Target, Range("B1:B10"))

If rngObserve Is Nothing Then
    Exit Sub
End If
For Each rngCell In rngObserve.Cells
    If Not Intersect(rngCell, rngObserve) Is Nothing Then
        If rngCell.Value = vbNullString Then
            rngCell.Interior.Color = xlNone
        ElseIf rngCell.Value < 3 And rgncell.Value > 0 Then
            rngCell.Interior.ColorIndex = 6 'yellow
        ElseIf rngCell.Value >= 3 Then
            rngCell.Interior.ColorIndex = 4 'green
        Else
            rngCell.Interior.ColorIndex = 3 'red
        End If
    End If
Next

End Sub

如 cmets 中所述，您只能有一个 Worksheet_Change 子例程。此代码应该可以满足您的需求：

Private Sub Worksheet_Change(ByVal Target As Range)

Dim rngObserve As Range, rngCell As Range

'PGCodeRider comment: I'd set these to named ranges instead of hard-coded addresses
Set rngObserve = Intersect(Target, Range("E18:G18, K1:K10"))

    If Not rngObserve Is Nothing Then

        For Each rngCell In rngObserve.Cells

    If rngCell.Value = vbNullString Then
        rngCell.Interior.Color = xlNone
    ElseIf rngCell.Value < 1 Then
        rngCell.Interior.ColorIndex = 3 'red
    ElseIf rngCell.Value >= 1 Then
        rngCell.Interior.ColorIndex = 4 'green
    Else
        rngCell.Interior.ColorIndex = 3 'red
    End If

        Next rngCell

    End If


Set rngObserve = Intersect(Target, Range("B1:B10"))

    If Not rngObserve Is Nothing Then

        For Each rngCell In rngObserve.Cells

            If rngCell.Value = vbNullString Then
                rngCell.Interior.Color = xlNone
            ElseIf rngCell.Value < 3 And rngCell.Value > 0 Then
                rngCell.Interior.ColorIndex = 6 'yellow
            ElseIf rngCell.Value >= 3 Then
                rngCell.Interior.ColorIndex = 4 'green
            Else
                rngCell.Interior.ColorIndex = 3 'red
            End If

        Next rngCell

    End If
End Sub
