excel中用vba让指定范围单元格一个一个随机变得完全透明

您可以使用以下VBA代码实现此功能：

Sub RandomlyMakeCellsTransparent()
    Dim cell As Range
    
    ' 循环遍历指定范围内的每个单元格，并将其设置为随机透明度
    For Each cell In Range("A1:C10")
        cell.Interior.ColorIndex = xlNone ' 将单元格背景色设为无色
        cell.Interior.TintAndShade = Rnd() ' 将单元格的透明度设为随机值
    Next cell
End Sub

这段代码会将指定范围内的每个单元格的背景色设为无色，并将其透明度设置为一个随机值。您可以将代码中的范围`"A1:C10"`替换为您想要操作的单元格范围。

您可以在Excel的Visual Basic Editor中打开您要编辑的工作簿，然后在工具栏中选择插入->模块，将下面的代码复制到模块中：

Sub RandomTransparency()
    Dim rng As Range
    For Each rng In Selection
        rng.Interior.ColorIndex = xlNone
        rng.Interior.Pattern = xlPatternNone
        rng.Font.ColorIndex = xlColorIndexNone
        rng.Font.ThemeColor = xlThemeColorLight1
        rng.Font.TintAndShade = 0
        rng.Font.Bold = False
        rng.Font.Italic = False
        rng.Font.Underline = xlUnderlineStyleNone
        rng.Font.Strikethrough = False
        rng.Font.FontStyle = "Regular"
        rng.Font.Size = 11
        rng.Font.ThemeFont = xlThemeFontMinor
        rng.Select
        ActiveSheet.Shapes.AddTextbox(msoTextOrientationHorizontal, rng.Left, rng.Top, rng.Width, rng.Height).TextFrame.Characters.Text = rng.Value
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextFrame.Characters.Font.Size = 0.1
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).Line.Visible = False
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).Fill.Visible = False
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextFrame2.VerticalAnchor = msoAnchorMiddle
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextFrame2.TextRange.Font.Fill.Visible = False
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextFrame2.TextRange.Font.Bold = False
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextFrame2.TextRange.Font.Italic = False
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextFrame2.TextRange.Font.Underline = msoFalse
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextFrame2.TextRange.Font.Size = 0.1
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextFrame2.TextRange.Font.Color.RGB = RGB(255, 255, 255)
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextFrame2.TextRange.Font.Name = "Arial"
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextFrame2.TextRange.Characters.Text = rng.Value
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextEffect.PresetShape = msoTextEffectShapeRound1
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextEffect.Alignment = msoTextEffectAlignmentCentered
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextEffect.FontSize = 1
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextEffect.FontBold = msoFalse
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextEffect.FontItalic = msoFalse
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextEffect.FontUnderline = msoFalse
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextEffect.FontName = "+mn-lt"
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextEffect.FontColor.RGB = RGB(255, 255, 255)
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextEffect.Perspective = msoTextEffectPerspectiveNone
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextEffect.TransformText = msoTextEffectTransformSlantUp
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextFrame2.AutoSize = msoAutoSizeShapeToFitText
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextFrame2.VerticalAnchor = msoAnchorMiddle
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextFrame2.TextRange.Font.Fill.Visible = False
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextFrame2.TextRange.Font.Bold = False
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextFrame2.TextRange.Font.Italic = False
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextFrame2.TextRange.Font.Underline = msoFalse
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextFrame2.TextRange.Font.Size = 0.1
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextFrame2.TextRange.Font.Color.RGB = RGB(255, 255, 255)
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextFrame2.TextRange.Font.Name = "Arial"
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).TextFrame2.TextRange.Characters.Text = rng.Value
        ActiveSheet.Shapes(ActiveSheet.Shapes.Count).Select
        Selection.ShapeRange.Fill.Transparency = WorksheetFunction.RandBetween(50, 100)
    Next rng
End Sub

然后，您需要选择要随机透明化的单元格范围，然后按下快捷键Alt+F8，选择RandomTransparency并点击运行即可。

excel中用vba让指定单元格随机变透明

可以使用VBA中的`Range.Interior.ColorIndex`属性来设定单元格颜色，其中颜色索引为0表示透明。要实现随机变透明的效果，可以使用`Rnd`函数生成一个0到1之间的随机数，并根据这个随机数来设定单元格颜色。以下是一个示例代码：

Sub RandomTransparency()
    Dim rng As Range
    Dim transparency As Double
    
    Set rng = Range("A1") '指定要变透明的单元格
    transparency = Rnd '生成随机透明度
    
    rng.Interior.ColorIndex = 0 '先将单元格设为透明
    rng.Interior.Transparency = transparency '再根据随机透明度设定颜色
End Sub

每次运行这个宏，都会随机改变指定单元格的透明度。
