如何使用空白单元格作为参考执行sumif？

Question

请参阅下面的示例数据:

Time        Date                Result
00:21.6     10/1/2012 1:43      FALSE
01:47.7     10/1/2012 2:13      FALSE
00:56.7     10/1/2012 2:49      FALSE
00:54.9     10/1/2012 3:43  
00:11.8     10/1/2012 3:43  
02:10.9     10/1/2012 3:46      FALSE
01:05.4     10/1/2012 3:58      FALSE
00:55.8     10/1/2012 4:53  
04:41.8     10/1/2012 4:52  
00:26.3     10/1/2012 4:58  
00:04.2     10/1/2012 4:58  
00:15.3     10/1/2012 4:59  
00:06.4     10/1/2012 4:57  
00:10.7     10/1/2012 4:56  
00:04.4     10/1/2012 4:56  
00:04.2     10/1/2012 4:57  
00:29.2     10/1/2012 4:57  
00:34.5     10/1/2012 4:56  
01:22.4     10/1/2012 4:55  
00:08.1     10/1/2012 4:55      FALSE
03:20.9     10/1/2012 4:51      FALSE
00:56.3     10/1/2012 5:42      FALSE
02:23.1     10/1/2012 5:51      
01:20.6     10/1/2012 5:48  
00:09.8     10/1/2012 5:49      FALSE
01:40.0     10/1/2012 7:47      FALSE
01:13.4     10/1/2012 8:11      FALSE
00:41.6     10/1/2012 9:49      FALSE
01:08.1     10/1/2012 11:56     FALSE

我需要执行某种类型的计算.如果结果中没有空白单元格,我需要结果旁边的时间单元格中的数据.但是如果结果列中有一个空白单元格,我需要在包含空白单元格的行和第一个包含空白单元格旁边的FALSE的单元格中执行时间总和.

请参阅下面的示例输出:

00:21.6     10/1/2012 1:43      FALSE       00:21.6

02:10.9     10/1/2012 3:46      FALSE       03:17.6(i.e., 00:54.9+00:11.8+02:10.9)

01:08.1     10/1/2012 11:56     FALSE       01:08.1

如果可以通过任何公式或使用Visual Basic编辑器,请告诉我.我现在正在手动执行此操作.我每天要处理大约10000-15000行.如果你帮助我,我可以节省很多时间并用它来学习新的东西.

如果您更喜欢使用VBA,可以试试这个:

Sub SmartRunningTotals()
    Dim rng As Range
    Dim cell As Range
    Dim lastRow As Long
    Dim totalTime As Double

    ' I'm assuming your time column is in column A
    lastRow = Range("A" & ActiveSheet.Rows.Count).End(xlUp).Row

    Set rng = Range("A2:A" & lastRow)

    For Each cell In rng
        totalTime = totalTime + cell.Value
        If cell.Offset(, 2).Value <> "" Then
            cell.Offset(, 3).Value = totalTime
            ' reset total after we write it to column D
            totalTime = 0
        End If
    Next

End Sub
