在工作表中查找最后一个非空行

Private Sub Get_Last_Used_Row_Index()
    Dim wS As Worksheet
    
    Set wS = ThisWorkbook.Sheets("Sheet1")
    Debug.Print LastRow_1(wS)
    Debug.Print LastRow_0(wS)
End Sub

你可以选择 2 个选项，如果你想知道工作表中是否没有数据：

• NO：使用 LastRow_1：你可以在 wS.Cells(LastRow_1(wS),...) 中直接使用它
• 是：使用 LastRow_0：在使用之前，你需要测试从函数获得的结果是否为 0

Public Function LastRow_1(wS As Worksheet) As Double
    With wS
        If Application.WorksheetFunction.CountA(.Cells) <> 0 Then
            LastRow_1 = .Cells.Find(What:="*", _
                                After:=.Range("A1"), _
                                Lookat:=xlPart, _
                                LookIn:=xlFormulas, _
                                SearchOrder:=xlByRows, _
                                SearchDirection:=xlPrevious, _
                                MatchCase:=False).Row
        Else
            LastRow_1 = 1
        End If
    End With
End Function

Public Function LastRow_0(wS As Worksheet) As Double
    On Error Resume Next
    LastRow_0 = wS.Cells.Find(What:="*", _
                            After:=ws.Range("A1"), _
                            Lookat:=xlPart, _
                            LookIn:=xlFormulas, _
                            SearchOrder:=xlByRows, _
                            SearchDirection:=xlPrevious, _
                            MatchCase:=False).Row
End Function
