我有以下代码,它们吸收了A列中的空行,然后删除了整行。我无法在2010上使用“特殊->空白->删除工作表行”功能,因为2007年的上限大约是8000个非连续行。在某些较旧的计算机上,此代码非常慢,大约需要40分钟才能完成(但可以完成此工作)。有没有更快的替代方法?
Private Sub Del_rows()
Dim r1 As Range, xlCalc As Long
Dim i As Long, j As Long, arrShts As Variant
With Application
xlCalc = .Calculation
.Calculation = xlCalculationManual
.ScreenUpdating = False
End With
arrShts = VBA.Array("Sheet1") 'add additional sheets as required
For i = 0 To UBound(arrShts)
With Sheets(arrShts(i))
For j = .UsedRange.Rows.Count To 2 Step -8000
If j - 7999 < 2 Then
.Range("A2:A" & j).SpecialCells(xlCellTypeBlanks).EntireRow.Delete
Else
.Range("A" & j, "A" & j - 7999).SpecialCells(xlCellTypeBlanks).EntireRow.Delete
End If
Next j
End With
Next i
Application.Calculation = xlCalc
此代码在100,000行上花费了不到一秒钟的时间(如果需要,请记录完整代码的操作):
Sub DeleteRows()
Application.ScreenUpdating = False
Columns(1).Insert xlToRight
Columns(1).FillLeft
Columns(1).Replace "*", 1
Cells.Sort Cells(1, 1)
Columns(1).SpecialCells(xlCellTypeBlanks).EntireRow.Delete
Columns(1).Delete
End Sub
[Rajiv,试试这个。这应该很快。
Option Explicit
Sub Sample()
Dim delrange As Range
Dim LastRow As Long, i As Long
With Sheets("Sheet1") '<~~ Change this to the relevant sheetname
'~~> Get the last Row in Col A
LastRow = .Range("A" & .Rows.Count).End(xlUp).Row
For i = 1 To LastRow
If Len(Trim(.Range("A" & i).Value)) = 0 Then
If delrange Is Nothing Then
Set delrange = .Rows(i)
Else
Set delrange = Union(delrange, .Rows(i))
End If
End If
Next i
If Not delrange Is Nothing Then delrange.Delete
End With
End Sub
编辑:
您还可以使用自动过滤器删除行。这非常快。我have n't都针对如此巨大的行测试了两个示例:)如果有任何错误,请告诉我。
Option Explicit Sub Sample() Dim lastrow As Long Dim Rng As Range With Sheets("Sheet1") lastrow = .Range("A" & .Rows.Count).End(xlUp).Row '~~> Remove any filters .AutoFilterMode = False With .Range("A1:A" & lastrow) .AutoFilter Field:=1, Criteria1:="" .Offset(1, 0).SpecialCells(xlCellTypeVisible).EntireRow.Delete End With '~~> Remove any filters ActiveSheet.AutoFilterMode = False End With End Sub
