通过自动过滤器删除时间过长

Question

我有大约8000多行.使用自动过滤器删除行需要几分钟.我认为autofilter是事实上快速删除的方式(而不是逐行循环).我怎样才能加快速度？有更快的方法吗？公平地说,一半的行被删除XD

With ThisWorkbook.Worksheets("Upload")
    lastRow = .Cells(.Rows.Count, "S").End(xlUp).Row
    Set dataRng = .Range(.Cells(4, 1), .Cells(lastRow, 19))
    dataRng.AutoFilter field:=19, Criteria1:="=0"
    Application.DisplayAlerts = False
    dataRng.Offset(1, 0).Resize(dataRng.Rows.Count - 1).SpecialCells(xlCellTypeVisible).Rows.Delete
    Application.DisplayAlerts = True
    .ShowAllData
End With

Answer 1

我将挑战潜在的假设,即AutoFilter是快速前进的方法 - 通常很难在变量数组上击败循环

这个演示展示了一种方法,在我的系统上处理8000多行,在亚秒内删除半个运行

Sub DEMO()
    Dim datrng As Range
    Dim dat, newdat
    Dim i As Long, j As Long, k As Long
    With ThisWorkbook.Worksheets("Upload")
        Set datrng = .Range(.Cells(1, 1), .Cells(.Rows.Count, "S").End(xlUp))
    End With
    dat = datrng.Value
    ReDim newdat(1 To UBound(dat, 1), 1 To UBound(dat, 2))
    j = 1
    For i = 1 To UBound(dat, 1)
        If dat(i, 19) <> 0 Then ' test for items you want to keep
            For k = 1 To UBound(dat, 2)
                newdat(j, k) = dat(i, k)
            Next
            j = j + 1
        End If
    Next

    datrng = newdat
End Sub
