如何基於Excel中的組將行連接到一個單元格中？
這是兩列的範圍，一列是班級列表，另一列是學生姓名列表。 如您所見，有些學生在同一堂課，有些則不在。 現在，我想將同一班級的學生連接到一個單元格中，如下面的屏幕截圖所示，如何在Excel中快速處理它？
用公式和過濾器功能分組和連接
在Excel中，您可以將公式應用於基於一列的串聯行，然後使用“篩選器”功能僅顯示結果。
備註：在執行以下步驟之前，您需要按類對數據進行排序。
1.在數據范圍旁邊的空白單元格中，例如C13，鍵入此公式 =IF(A13=A12,C12&", "&B13,B13)， 按 Enter 鍵，然後拖動填充手柄將公式填充到單元格中。
在公式中，A13是“類別”列中的第一個數據，B13是“名稱”列中的第一個數據，“，”是用於分隔連接內容的分隔符。
2.然後在下一列D13中鍵入此公式 =IF(A13<>A14,"Last","") ，然後向下拖動填充手柄以將公式應用於所需的單元格。
3.現在選擇所有數據范圍，包括公式，然後單擊 數據 > Filter 加上 Filter icons 數據。
4。 點擊 Filter icon 在最後一個公式標題中，檢查 Last 僅從下拉列表中選中復選框，然後單擊 OK.
現在結果顯示如下，如果不需要，您可以刪除最後一個幫助器列。
分組並連接VBA代碼
這是一個VBA代碼，也可以處理此工作。
1。 按 Alt + F11 啟用 Microsoft Visual Basic for Applications 窗口。
2.然後在窗口中，單擊 Tools > References 啟用 References 對話框，然後檢查 Microsoft Scripting Runtime。 看截圖：
3。 點擊 OK，然後點擊 Insert > Module 在VBA窗口中，然後將以下VBA代碼複製並粘貼到 Module 腳本。 看截圖：
VBA：根據組將行連接到一個單元格中
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", vbInformation, "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.
5. Click OK to select the key column you want to group based on.
6. Click OK, now the result is shown as below:
