vba - 在 VBA 中循环列时选择单元格

Question

我有一个可以格式化多页 Excel 文档的宏。每张纸上都有一个数据表，我尝试根据标题行(第 1 行)的内容对各列进行颜色编码。

我想选择列中的第二个单元格，直到最后一行数据，并设置背景颜色。我目前有一些看起来像这样的东西:

For Each ws In ActiveWorkbook.Worksheets
    With ws
        .Activate

        ' Convert to table
        If .UsedRange.ListObject Is Nothing Then
            .ListObjects.Add SourceType:=xlSrcRange,
                             Source:=.UsedRange, 
                             xllistobjecthasHeaders:=xlYes, 
                             TableStyleName:="Table Style 1"
        End If

        ' Additional Formatting
        ...

        ' Adjust columns
        For Each col In .UsedRange.Columns
            Header = col.Cells(1, 1)

            ' Additional formatting that works
            ...

            Dim col_color As Variant

            ' Color Code
            If Header = "A" Then
                col_color = xlThemeColorAccent6 ' Orange
            ElseIf Header ="B" Then
                col_color = xlThemeColorLight2 ' Blue
            ElseIf Header = "C" Then
                col_color = xlThemeColorAccent4 ' Purple
            ElseIf Header ="D" Then
                col_color = xlThemeColorAccent3 ' Green
            ElseIf Header = "E" Then
                col_color = xlThemeColorAccent2 ' Red
            End If

            Range(col.Cells(2, 1)).Select ' ERROR HERE
            Range(Selection, Selection.End(xlDown)).Select
            With Selection.Interior
                .Pattern = xlSolid
                .PatternColorIndex = xlAutomatic
                .ThemeColor = col_color
                .TintAndShade = 0.8
                .PatternTintAndShade = 0
            End With


        Next col

我在 Range(col.Cells(2, 1)).Select 上收到以下错误:“对象 '_Global' 的方法 'Range' 失败”。

我的问题是如何在循环的当前列迭代中正确选择第二个单元格？

Answer 1

I would like to select the 2nd cell in the column, up to the last row of data, and set the background color.

无需进行选择来设置背景颜色。正确声明范围变量并使用它:

Dim formatRange as Range
Set formatRange = Range(col.Cells(2, 1), col.Cells(2, 1).End(xlDown) )

With formatRange.Interior
    .Pattern = xlSolid
    .PatternColorIndex = xlAutomatic
    .ThemeColor = col_color
    .TintAndShade = 0.8
    .PatternTintAndShade = 0
End With

发生错误是因为您只向 Range 方法传递了一个参数，该参数是一个单元格，其默认属性是它的 Value，所以除非col.Cells(2,1) 包含有效范围地址字符串作为其值，这总是会失败。您可以通过在单个Select中将两个参数传递给Range来避免这种情况:

Range(col.Cells(2, 1), col.Cells(2, 1).End(xlDown)).Select
With Selection.Interior
    ...

或者:

 col.Cells(2, 1).Select
 Range(Selection, Selection.End(xlDown)).Select
 With Selection.Interior
    ...    

或者甚至:

 col(2,1).Select
 Range(Selection, Selection.End(xlDown)).Select
 With Selection.Interior
    ...     

但是你不应该做这些事情:

这几乎是普遍的better to avoid Activate/Select .
