如何编写 VBA 代码来删除工作簿中所有工作表的特定列？

Question

我正在使用 Excel 2016，我是 VBA 的新手。我需要编写 VBA 代码来删除 Excel 工作簿中所有工作表的特定列。

让我们假设我需要删除的列是所有工作表的 B, D, G, H, AM, AZ 列。

我怎样才能做到这一点？

Answer 1

试试这个：

Sub DeleteCols()
    Dim sh As Worksheet
    'as mentioned in comments by FunThomas, deleting should be done "backwards", i.e. for right to left
    For Each sh In Worksheets
        sh.Columns("AZ").Delete
        sh.Columns("AM").Delete
        sh.Columns("H").Delete
        sh.Columns("G").Delete
        sh.Columns("D").Delete
        sh.Columns("B").Delete
    Next
End Sub

或者，您可以使用：

Sub ClearCols()
    Dim sh As Worksheet
    For Each sh In Worksheets
        sh.Columns("B").Clear
        sh.Columns("D").Clear
        sh.Columns("G").Clear
        sh.Columns("H").Clear
        sh.Columns("AM").Clear
        sh.Columns("AZ").Clear
    Next
End Sub

另一种方法是（@Peh 建议）：

sh.Range("B:B,D:D,G:H,AM:AM,AZ:AZ").Delete

在许多列上应该更快（您可以类比地使用 Clear 方法）。

Answer 2

通过数组方法并删除 "backwards"

Sub DeleteCols() 
    Dim sh As Worksheet 
    Dim arr as Variant
    arr = Array("AZ", "AM", "H", "G", "D", "B")
    For Each sh In Worksheets 
        For Each element in arr
            sh.Columns(element).Delete
        Next
    Next 
End Sub

Answer 3

我会对以上答案做一些小的调整：

尝试像这样一次性全部删除：

Sub DEL()

Dim SHT As Worksheet
For Each SHT In Worksheets
    SHT.Range("B:B,D:D,G:G,H:H,AM:AM,AZ:AZ").EntireColumn.Delete
Next SHT

End Sub

编辑：我看到我的上述建议已经在答案中实现，所以我将添加另一个选项，您可以在没有任何循环的情况下执行此操作（应该是更快的方法）：

Sheets.Select 'Selects all sheets at once
Range("B:B,D:D,G:G,H:H,AM:AM,AZ:AZ").Select 'Select all the appropriate columns you want to delete at once
Selection.Delete Shift:=xlToLeft 'Deletes all columns on all sheets at once

您将看到必须取消的工作表和列的选择。

比较性能：

All-at-once - Total Sheets: 1,001 - Time: 29.137 sec (by JvdV)
One-by-one  - Total Sheets: 1,001 - Time: 72.164 sec

这是测试

Option Explicit

Public Sub DeleteColumns()
    Dim thisWs As Worksheet, thisCell As Range, t As Double, msg As String

    t = Timer
    Application.ScreenUpdating = False
    Set thisWs = ActiveSheet
    Set thisCell = ActiveCell

        ThisWorkbook.Worksheets.Select      'Selects all sheets at once

        Range("B1, D1, G1:H1, AM1, AZ1").EntireColumn.Select  'All columns on all sheets

        Selection.Delete Shift:=xlToLeft    'Deletes all columns on all sheets at once

    Cells(1).Select     'Selects A1 on all sheets
    thisWs.Select
    thisCell.Activate   'Activates initial range
    Application.ScreenUpdating = True

    msg = "All-at-once - Total Sheets: " & Format(Sheets.Count, "#,###")
    Debug.Print msg & " - Time: " & Format(Timer - t, "0.000") & " sec"
    'All-at-once - Total Sheets:   101 - Time:  2.469 sec
    'All-at-once - Total Sheets:   501 - Time: 13.484 sec
    'All-at-once - Total Sheets: 1,001 - Time: 29.137 sec
End Sub

Sub DeleteCols()
    Dim sh As Worksheet, t As Double, msg As String

    t = Timer
    For Each sh In Worksheets
        sh.Columns("AZ").Delete
        sh.Columns("AM").Delete
        sh.Columns("H").Delete
        sh.Columns("G").Delete
        sh.Columns("D").Delete
        sh.Columns("B").Delete
    Next

    msg = "One-by-one - Total Sheets: " & Format(Sheets.Count, "#,###")
    Debug.Print msg & " - Time: " & Format(Timer - t, "0.000") & " sec"
    'One-by-one - Total Sheets:   101 - Time:  3.609 sec
    'One-by-one - Total Sheets:   501 - Time: 26.633 sec
    'One-by-one - Total Sheets: 1,001 - Time: 72.164 sec
End Sub

Public Sub MakeWS()
    Dim i As Long

    Application.ScreenUpdating = False
    With ThisWorkbook.Worksheets
        For i = .Count To 1000
            .Item(1).Copy After:=.Item(i)
            ActiveSheet.Name = i + 1
        Next
    End With
    Application.ScreenUpdating = True
End Sub
