这将是我的代码，但如果我有超过 5000 行和 1 列，则需要一生。有没有办法减少查询时间？

Sub InsertRows() 
    Dim numRows As Integer 
    Dim r As Long 

    Application.ScreenUpdating = False 

    r = Cells(Rows.Count, "A").End(xlUp).Row 
    numRows = 11 

    For r = r To 1 Step -1 
        ActiveSheet.Rows(r + 1).Resize(numRows).Insert 
    Next r 

    Application.ScreenUpdating = True 
End Sub

这花费了 < 1 秒。

Sub InsertRows()

Dim numberOfValues As Long
Dim i As Long
Dim values As Variant

Const numberOfEmptyRows As Long = 11

Application.ScreenUpdating = False

' count values in column A
numberOfValues = Cells(Rows.Count, "A").End(xlUp).Row

' populate array with numbers
ReDim values(1 To numberOfValues, 1 To 1)
For i = 1 To numberOfValues
  values(i, 1) = i
Next i

' I know there is a better way to do this part...
Range(Cells(1, 2), Cells(numberOfValues, 2)).Value = values
For i = 1 To numberOfEmptyRows - 1
  Range(Cells(Rows.Count, "B").End(xlUp).Offset(1, 0), Cells(Rows.Count, "B").End(xlUp).Offset(numberOfValues, 0)).Value = values
Next i

' sort by values inserted in column B
Range(Cells(1, 1), Cells(Rows.Count, "B").End(xlUp)).Sort Key1:=Range("B1"), _
        Order1:=xlAscending, Header:=xlGuess, _
        OrderCustom:=1, MatchCase:=False, Orientation:=xlTopToBottom, _
        DataOption1:=xlSortNormal

Columns("B:B").EntireColumn.Delete

Application.ScreenUpdating = True
End Sub

此代码使用辅助列（在本例中为 B）在目标范围旁边插入一个数字序列。然后它在自身下方添加相同的数字 N 次，并对该列进行排序。最后，它删除该列。这就是您可以快速将空白行插入任何数据集中的方法。

更改Const numberOfEmptyRows As Long = 11是否要插入更多/更少的空白行。在达到 Excel 的行数限制之前，这种技术可以处理的记录数（以及可以插入的空白行数）是有限制的。

Jimmy, your code is very nice. But if there isn't any content in 'A' column while the other columns have some the result of sorting will go wrong.

So, I will use UsedRange to get numberOfValues as below.

 Set r2Arrange = ActiveSheet.UsedRange

count values in column A:

numberOfValues = r2Arrange.Rows.Count
