excel - 删除电子表格中行的有效方法

Question

有没有比我目前使用的更好的方法来删除 Excel 电子表格中的行？

在电子表格上，我运行一个宏，如果特定单元格中的数字为“0”，则删除一行。

Public Sub deleteRowsIfZero(colDelete As Integer)
Dim r As Long
Application.ScreenUpdating = False

For r = Cells(Rows.Count, colDelete).End(xlUp).Row To 1 Step -1
    If Cells(r, colDelete).Value = "0" Then Rows(r).Delete
Next r
Application.ScreenUpdating = True
End Sub

这行得通，但是对于 700 多行的电子表格，它可能会很慢。有没有更有效的方法来做到这一点？

提前感谢您的任何建议。

干杯

我会使用一个连续的范围并一次性删除它:

Public Sub deleteRowsIfZero(strSeekValue As String)
Dim lngRowsToDelete() As Long
Dim strRowsToDelete() As String
Dim x As Long, y As Long, n As Long, z As Long

On Error GoTo err_

'get the extent of the workbook range
x = Me.UsedRange.Rows.Count

n = -1

'switch off screen updating and calculation
Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual

'starting from row 1, look for the strSeekValue in column A, keep going till x is reached
For y = 1 To x
    If Me.Range("A" & y).Value = strSeekValue Then 'if we find one, pop the row number into the array
        n = n + 1
        ReDim Preserve lngRowsToDelete(0 To n)
        lngRowsToDelete(n) = y
    End If
Next y

'if none were found, don't do the next bit
If n = -1 Then GoTo err_

'create a string of all the rows we found
z = 0
ReDim strRowsToDelete(z)
For y = 0 To n
    strRowsToDelete(z) = strRowsToDelete(z) & lngRowsToDelete(y) & ":" & lngRowsToDelete(y) & ","
    If Len(strRowsToDelete(z)) > 240 Then 'As A.Webb points out, the 255 limit will be a problem here
        strRowsToDelete(z) = Left(strRowsToDelete(z), Len(strRowsToDelete(z)) - 1) 'drop the trailing comma
        z = UBound(strRowsToDelete) + 1 'resize the array
        ReDim Preserve strRowsToDelete(0 To z)
    End If
Next y

For y = z To 0 Step -1
    If Right(strRowsToDelete(z), 1) = "," Then strRowsToDelete(z) = Left(strRowsToDelete(z), Len(strRowsToDelete(z)) - 1)
    'now delete the rows
    Me.Range(strRowsToDelete(y)).EntireRow.Delete
Next y

err_:
'assumes calculation was set to auto
Application.Calculation = xlCalculationAutomatic
If Err Then Debug.Print Err.Description
Application.ScreenUpdating = True
End Sub


'run sub foo
Sub foo()
deleteRowsIfZero "0"
End Sub
