Question

我想创建一个excel表，其中数据应输入Row- * - Column-A。

将数据输入Row-N :: Column-A后，我想将输入的数据与从B列可用的下拉列表中选择的条目相关联。

现在，Column-B列表中的每个项目都有一个专用列表。如果我在Column-B中选择了Item-X，我应该可以在Column-C中选择一个专用于Item-X的列表中的项目。

这是怎么做到的？

以下代码只需粘贴源列中的数据即可帮助您创建相关列表。为简单起见，我们将上面的列表复制并粘贴到Excel表格的A列和B列中，比如Sheet1。但是，在我们这样做之前，我们必须将以下代码粘贴到图纸代码区域中。可以通过从主工作表中按 Alt + F11 来访问工作表代码区域。

Option Explicit

Private Sub Worksheet_Change(ByVal Target As Range)
    Dim i As Long, LastRow As Long, n As Long
    Dim MyCol As Collection
    Dim SearchString As String, TempList As String

    Application.EnableEvents = False

    On Error GoTo Whoa

    '~~> Find LastRow in Col A
    LastRow = Range("A" & Rows.Count).End(xlUp).Row

    If Not Intersect(Target, Columns(1)) Is Nothing Then
        Set MyCol = New Collection

        '~~> Get the data from Col A into a collection
        For i = 1 To LastRow
            If Len(Trim(Range("A" & i).Value)) <> 0 Then
                On Error Resume Next
                MyCol.Add CStr(Range("A" & i).Value), CStr(Range("A" & i).Value)
                On Error GoTo 0
            End If
        Next i

        '~~> Create a list for the DV List
        For n = 1 To MyCol.Count
            TempList = TempList & "," & MyCol(n)
        Next

        TempList = Mid(TempList, 2)

        Range("D1").ClearContents: Range("D1").Validation.Delete

        '~~> Create the DV List
        If Len(Trim(TempList)) <> 0 Then
            With Range("D1").Validation
