下面的代碼允許我刪除行，如果一個單元格包含某些值。現在由於某種原因，我花了很多時間（30分鐘和計數）。更快刪除行
' to delete data not meeting criteria
Worksheets("Dashboard").Activate
n1 = Range("n1")
n2 = Range("n2")
Worksheets("Temp Calc").Activate
lastrow = Cells(Rows.Count, 1).End(xlUp).Row
For z = lastrow To 2 Step -1
If Cells(z, 6).Value = "CNF" Or Cells(z, 4).Value <= n1 Or Cells(z, 3).Value >= n2 Then
Rows(z).Delete
End If
Next z
谷歌搜索，並與論壇成員SAM一些談話給我提供了兩個選項
- 使用過濾器。（我也想用這個）。
使用數組來存儲整個工作表，然後複製只符合我的條件的數據。他非常友好，可以幫我拿出下面的代碼。但是我不熟悉處理數組中的數據。
lastrow = Cells(Rows.Count, 1).End(xlUp).Row lastCol = Cells(1, Column.Count).End(xlRight).Row arr1 = Range("A1:Z" & lastrow) ReDim arr2(1 To UBound(arr1, 1), 1 To UBound(arr1, 2)) j = j + 1 For i = 1 To UBound(arr1, 1) If arr1(i, 6) <> "CNF" And arr1(i, 4) > n1 And arr1(i, 3) < n2 Then For k = 1 To lastCol arr2(j, k) = arr1(i, k) Next k j = j + 1 End If Next i Range(the original bounds) = arr2
我的問題是是否有比上面提到的那些以外的數組刪除行的一個更快的方法？或者是數組或篩選我所擁有的最佳選擇。我樂於接受建議。
更新我的新代碼看起來像這樣。它不會過濾日期範圍，如果它們是硬編碼的，任何人都可以告訴我我做錯了什麼？

我會使用過濾是非常快... –
我讀來實現關於它，但沒有其他辦法？ 哦，這裏是一個踢球者，相同的代碼昨天在2分鐘內工作，今天它已經45分鐘，仍然計數 – mathew
爲同一組數據？差異太大，可能是你的代碼或數據有問題... –
