excel - 遍历列过滤时可见的数据

Question

以下代码是我经过大量研究和辛勤工作后编写的，但是我现在发现这没有用，因为我在 worksheetsheet 中有多个过滤器.我不想遍历工作表中的所有数据，我只想遍历过滤时可见的数据。但是，使用我的代码，它会遍历所有行。一次我最多过滤 5 列。
在 dt = CDate(Sheets("Sheet5").Range("P2").Value)我已经给了 P2，但是当我过滤它时它可能不可见，我不想检查这个单元格中的数据。

Sub FindDuration()

Dim totalDuration As Single
Dim dt As Date
Dim nextDt As Date
Dim maxDt As Date
Dim DateDiff
Dim lr As Long
Dim lrw As Long
Dim lr1 As Long
Dim i As Long

totalDuration = 0
dt = 0
lr1 = ThisWorkbook.Sheets("Sheet5").Range("A" & Rows.Count).End(xlUp).Row

dt = CDate(Sheets("Sheet5").Range("P2").Value)
maxDt = dt + 1
  
For i = 2 To lr1

    DateDiff = maxDt - dt
 
    If DateDiff <= 1 And nextDt <= maxDt Then
        totalDuration = totalDuration + Sheets("Sheet5").Range("G" & i).Value
        nextDt = CDate(Sheets("Sheet5").Range("P" & i + 1).Value)
    Else
        lrw = ThisWorkbook.Sheets("Chart").Range("A" & Rows.Count).End(xlUp).Row
        Sheets("Chart").Range("A" & lrw + 1).Value = totalDuration
        totalDuration = Sheets("Sheet5").Range("G" & i).Value
        dt = CDate(Sheets("Sheet5").Range("P" & i).Value)
        maxDt = dt + 1

    End If

Next i
lrw = ThisWorkbook.Sheets("Chart").Range("A" & Rows.Count).End(xlUp).Row
Sheets("Chart").Range("A" & lrw + 1).Value = totalDuration

End Sub

我知道这段代码并不完美，因为我不是 VBA 专家。
编辑:
您在下图中看到的只是示例数据。 J 和 K 列中的值(在我们的代码 G 和 P 中)是我们所拥有的 L、N、O 是我们想要的。我们几乎已经用我们的代码完成了“要添加的总持续时间”，而 N 和 O 列是我遇到问题的地方。
