如何使用VBA根据条件删除Excel中的行？

Question

我目前正在构建一个宏来格式化数据表并删除不适用的数据行。具体来说，我希望删除 Column L = "ABC" 的行以及删除 Column AA <> 的行。 “DEF”。

到目前为止，我已经实现了第一个目标，但还没有实现第二个目标。现有代码是：

Dim LastRow As Integer
Dim x, y, z As Integer
Dim StartRow, StopRow As Integer

For x = 0 To LastRow
    If (Range("L1").Offset(x, 0) = "ABC") Then
    Range("L1").Offset(x, 0).EntireRow.Delete
    x = x - 1

End If

Answer 1

通常使用自动筛选比循环范围要快得多

下面的代码创建一个工作列，然后使用公式来检测删除条件，然后自动筛选并删除结果记录

工作列放置一个公式

=OR(L1= “ABC”，AA1<>“DEF”）
到第一个空白列的第 1 行，然后向下复制到真正使用的范围。然后使用自动过滤器快速删除任何 TRUE 记录

Sub QuickKill()
    Dim rng1 As Range, rng2 As Range, rng3 As Range
    Set rng1 = Cells.Find("*", , xlValues, , xlByColumns, xlPrevious)
    Set rng2 = Cells.Find("*", , xlValues, , xlByRows, xlPrevious)
    Set rng3 = Range(Cells(rng2.Row, rng1.Column), Cells(1, rng1.Column))
    Application.ScreenUpdating = False
    Rows(1).Insert
    With rng3.Offset(-1, 1).Resize(rng3.Rows.Count + 1, 1)
        .FormulaR1C1 = "=OR(RC12=""ABC"",RC27<>""DEF"")"
        .AutoFilter Field:=1, Criteria1:="TRUE"
        .EntireRow.Delete
        On Error Resume Next
        'in case all rows have been deleted
        .EntireColumn.Delete
        On Error GoTo 0
    End With
    Application.ScreenUpdating = True
End Sub

Answer 2

使用循环：

Sub test()
    Dim x As Long, lastrow As Long
    lastrow = Cells(Rows.Count, 1).End(xlUp).Row
    For x = lastrow To 1 Step -1
        If Cells(x, 12).Value = "ABC" or Cells(x, 27) <> "DEF" Then
            Rows(x).Delete
        End If
    Next x
End Sub

使用自动过滤器（可能更快）：

Sub test2()
    Range("a1").AutoFilter Field:=12, Criteria1:="ABC", Operator:=xlOr, _
                           Field:=28, Criteria1:="<>""DEF"""
    'exclude 1st row (titles)
    With Intersect(Range("a1").CurrentRegion, _
                   Range("2:60000")).SpecialCells(xlCellTypeVisible)
        .Rows.Delete
    End With
    ActiveSheet.ShowAllData
End Sub

Answer 3

编号 12 的单元格为“L”，编号 27 的单元格为“AA”

Dim x As Integer

x = 1

Do While x <= ActiveSheet.Cells.SpecialCells(xlCellTypeLastCell).Row

    If (Cells(x, 12) = "ABC") Then
    ActiveSheet.Rows(x).Delete
    Else
        If (Cells(x, 27) <> "DEF") And (Cells(x, 27) <> "") Then
        ActiveSheet.Rows(x).Delete
        Else
        x = x + 1
        End If
    End If

Loop

End Sub

Answer 4

Sub test()

    Dim bUnion As Boolean
    Dim i As Long, lastrow As Long
    Dim r1 As Range
    Dim v1 As Variant

    lastrow = Cells(Rows.Count, 1).End(xlUp).Row
    v1 = ActiveSheet.Range(Cells(1, 12), Cells(lastrow, 27)).Value2
    bUnion = False

    For i = 1 To lastrow
        If v1(i, 1) = "ABC" Or v1(i, 16) <> "DEF" Then
            If bUnion Then
                Set r1 = Union(r1, Cells(i, 1))
            Else
                Set r1 = Cells(i, 1)
                bUnion = True
            End If
        End If
    Next i
    r1.EntireRow.Delete

End Sub
