如何基于Excel中的组将行连接到一个单元格中？
这是两列的范围，一列是班级列表，另一列是学生姓名列表。 如您所见，有些学生在同一堂课，有些则不在。 现在，我想将同一班级的学生连接到一个单元格中，如下面的屏幕截图所示，如何在Excel中快速处理它？
用公式和过滤器功能分组和连接
分组并连接VBA代码
分组并连接“高级合并行”
用公式和过滤器功能分组和连接
在Excel中，您可以将公式应用于基于一列的串联行，然后使用“筛选器”功能仅显示结果。
备注：在执行以下步骤之前，您需要按类对数据进行排序。
1.在数据范围旁边的空白单元格中，例如C13，键入此公式 =IF(A13=A12,C12&", "&B13,B13)， 按 Enter
键，然后拖动填充手柄将公式填充到单元格中。
在公式中，A13是“类别”列中的第一个数据，B13是“名称”列中的第一个数据，“，”是用于分隔连接内容的分隔符。
2.然后在下一列D13中键入此公式 =IF(A13<>A14,"Last","")
，然后向下拖动填充手柄以将公式应用于所需的单元格。
3.现在选择所有数据范围，包括公式，然后单击 Data > Filter 添加 Filter icons
数据。
4。 点击 Filter icon 在最后一个公式标题中，检查 Last 仅从下拉列表中选中复选框，然后单击 OK
.
现在结果显示如下，如果不需要，您可以删除最后一个帮助器列。
分组并连接VBA代码
这是一个VBA代码，也可以处理此工作。
1。 按 Alt + F11 启用 Microsoft Visual Basic for Applications 窗口。
2.然后在窗口中，单击 Tools > References 启用 References 对话框，然后检查 Microsoft Scripting Runtime
。 看截图：
3。 点击 OK和点击 Insert > Module 在VBA窗口中，然后将以下VBA代码复制并粘贴到 Module 脚本。 看截图：
VBA：根据组将行连接到一个单元格中
Sub ConcatenateCellsIfSameValues()

Dim I As Long
Dim J As Long
Dim xRg As Range
Dim xRgKey As Range
Dim xRgVal As Range
Dim xStr As String
Dim xDic As New Dictionary
On Error Resume Next
Set xRg = Application.InputBox("Select data range", "KuTools for Excel", Selection.Address, , , , , 8)
If xRg Is Nothing Then Exit Sub
Set xRgKey = Application.InputBox("Select key column", "KuTools for Excel", xRg.Columns(1).Address, , , , , 8)
If xRgKey Is Nothing Then
MsgBox "Key column cannot be empty", vb***mation, "KuTools for Excel"
End If
Set xRgVal = xRg(1).Offset(, 1).Resize(xRg.Rows.Count, xRg.Columns.Count - 1)
For I = 1 To xRgKey.Count
If I > xRgKey.Count Then Exit For
xStr = ""
For J = 1 To xRgVal.Columns.Count
xStr = xStr & " " & xRgVal(I, J)
Next
If xDic.Exists(xRgKey(I).Text) Then
xDic(xRgKey(I).Text) = xDic(xRgKey(I).Text) & xStr
xRgKey(I).EntireRow.Delete
I = I - 1
Else
xDic.Add xRgKey(I).Text, xStr
End If
Next
For I = 1 To xRgVal.Count
xRgVal(I).Value = xDic(xRgKey(I).Text)
Next
End Sub
4. Press F5 key, and select the data range you use in the popping dialog.
