选择“保存”后如何运行宏？

我正在设置一个文档，以便在特定单元格包含值的情况下删除行。我希望在选择“保存”按钮时运行此代码。我需要在vba脚本中添加些什么才能实现此目的？

我已经搜索了多个站点并尝试了一些建议的解决方案，但没有找到一个可行的解决方案。

HideRows_BeforeSave()
Dim beginRow As Long
Dim endRow As Long
Dim chkCol As Long
Dim rowCnt As Long
Dim rngResult As Range
Dim ws As Worksheet
beginRow = 3
endRow = 38
chkCol = 14
Set ws = ThisWorkbook.Worksheets("Travel Expense Codes")
For rowCnt = beginRow To endRow
If Cells(rowCnt,chkCol).Value = "X" Then
Cells(rowCnt,chkCol).EntireRow.Hidden = True
Else
Cells(rowCnt,chkCol).EntireRow.Hidden = False
End If
Next rowCnt


将此代码插入“ ThisWorkbook”对象时，运行宏时没有任何响应。当插入“模块”时，我可以使宏运行，但不能通过“保存”选项使其运行。

您可以试试吗？正如@braX所建议的那样，您需要从最后一行开始，一直到第一行。该代码位于“ ThisWorkbook”中，见红色圆圈。

Option Explicit
Private Sub Workbook_BeforeSave(ByVal SaveAsUI As Boolean,Cancel As Boolean)
Dim beginRow As Long,endRow As Long,chkCol As Long,rowCnt As Long
Dim rngResult As Range
Dim ws As Worksheet
beginRow = 3
endRow = 38
chkCol = 14
Set ws = ThisWorkbook.Worksheets("Travel Expense Codes")
For rowCnt = endRow To beginRow Step -1
If Cells(rowCnt,chkCol).Value = "X" Then
ws.Cells(rowCnt,chkCol).EntireRow.Delete
End If
Next rowCnt
End Sub
