如何在excel vba项目中根据标题选择列

Question

我目前正在处理一个 Excel VBA 项目，该项目可以合并来自多个工作簿的数据。

工作簿的列相同，但行长可变。

我只想从标题为“学校名称”、“参与者”和“状态”的列中提取数据。这些是单元格 B2、G2 和 H2。因此，实际上，我只想要 B、G 和 H 列中的数据。

目前，我使用设定范围 (B3:H80) 提取数据，然后删除不需要的列。如何将源范围编辑为 .usedrange 并进行相应的编辑？

我附上了下面的代码。感谢您的帮助！

Private Sub MergeAllWorkbooks()
Dim MyPath As String, FilesInPath As String
Dim MyFiles() As String
Dim SourceRcount As Long, FNum As Long
Dim mybook As Workbook, BaseWks As Worksheet
Dim sourceRange As Range, destrange As Range
Dim rnum As Long, CalcMode As Long


' Change this to the path\folder location of your files.
MyPath = "C:\Users\" & Environ("username") & "\Dropbox\Folder1\"

' Add a slash at the end of the path if needed.
If Right(MyPath, 1) <> "\" Then
    MyPath = MyPath & "\"
End If

' If there are no Excel files in the folder, exit.
FilesInPath = Dir(MyPath & "*.xl*")
If FilesInPath = "" Then
    MsgBox "No files found"
    Exit Sub
End If

' Fill the myFiles array with the list of Excel files
' in the search folder.
FNum = 0

Answer 1

改变

destrange.Value = SourceRange.Value

到

destrange.Columns(1).Value = SourceRange.Columns(1).Value
destrange.Columns(2).Value = SourceRange.Columns(6).Value
destrange.Columns(3).Value = SourceRange.Columns(7).Value
