Question

我希望能够组合第一列中的值匹配的行，以便将非空单元格的值合并为一行。 E.g：

Mary Smith, A, [blank cell]

Mary Smith, [blank cell], B

- ＆GT;

Mary Smith A B

我已尝试使用以下代码：

Dim RowNum As Long, LastRow As Long

Application.ScreenUpdating = False

RowNum = 4

LastRow = Cells.SpecialCells(xlCellTypeLastCell).Row

Range("A4", Cells(LastRow, 13)).Select

For Each Row In Selection

 With Cells

If Cells(RowNum, 1) = Cells(RowNum + 1, 1) Then

 Cells(RowNum + 1, 1).Copy Destination:=Cells(RowNum, 1)

 Cells(RowNum + 1, 2).Copy Destination:=Cells(RowNum, 2)

 Cells(RowNum + 1, 3).Copy Destination:=Cells(RowNum, 3)

Cells(RowNum + 1, 4).Copy Destination:=Cells(RowNum, 4)

Cells(RowNum + 1, 5).Copy Destination:=Cells(RowNum, 5)

Cells(RowNum + 1, 6).Copy Destination:=Cells(RowNum, 6)

 Cells(RowNum + 1, 7).Copy Destination:=Cells(RowNum, 7)

 Cells(RowNum + 1, 8).Copy Destination:=Cells(RowNum, 8)

 Cells(RowNum + 1, 9).Copy Destination:=Cells(RowNum, 9)

 Cells(RowNum + 1, 10).Copy Destination:=Cells(RowNum, 10)

Cells(RowNum + 1, 11).Copy Destination:=Cells(RowNum, 11)

 Cells(RowNum + 1, 12).Copy Destination:=Cells(RowNum, 12)

 Cells(RowNum + 1, 13).Copy Destination:=Cells(RowNum, 13)

Rows(RowNum + 1).EntireRow.Delete

End If

End With

RowNum = RowNum + 1

Next Row

Application.ScreenUpdating = True

'

End Sub

这很好地整合了数据，因此第一列中只有唯一值，但是，当复制行时，空白单元格的值会复制到填充的单元格中，这不是我想要的。因此，例如，在上述数据上运行此宏将产生：

Mary Smith, A, [blank cell]

Mary Smith, [blank cell], B

- ＆GT;

Mary Smith, A, [blank cell]

任何了解我如何修改上述代码（或使用更优雅的东西）的任何见解都将不胜感激!!

Answer 1

这将很快完成：

Sub foo()
    Dim ws As Worksheet
    Dim lstrow As Long

    Set ws = Sheets("Sheet1") ' Change to your sheet

    With ws
        lstrow = .Range("A" & .Rows.Count).End(xlUp).Row
        With .Range("B4:M" & lstrow)
            .Offset(, 26).FormulaR1C1 = "=IFERROR(INDEX(R4C[-26]:R" & lstrow & "C[-26],MATCH(1,INDEX((R4C1:R" & lstrow & "C1 = RC1)*(R4C[-26]:R" & lstrow & "C[-26] <>""""),),0)),"""")"
            ws.Calculate
            .Value = .Offset(, 26).Value
            .Offset(, 26).ClearContents
        End With
        With .Range("A4:M" & lstrow)
            .Value = .Value
            .RemoveDuplicates 1, xlGuess
        End With
    End With

End Sub

它基本上使用公式：=INDEX(B$4:B$4,MATCH(1,INDEX(($A$4:$A$4 = $A4)*(B$4:B$4 <>""),),0))来查找所有值。将这些公式放在空白列中，然后将数据复制回来并删除重复项。

这将同时执行所有13列。

它也不关心A列中的值重复多少次。该列中可能有4 Mary Smith个。它将获取每列中的第一个值并使用它。

尝试以下代码

Sub test()
    LastRow = Range("A" & Rows.Count).End(xlUp).Row
    For i = 4 To LastRow
        If ((Range("A" & i).Value = Range("A" & i + 1).Value) And (Range("B" & i).Value <> Range("B" & i + 1).Value) And ((Range("B" & i).Value = "") Or (Range("B" & i + 1).Value = "")) And (Range("C" & i).Value <> Range("C" & i + 1).Value) And ((Range("C" & i).Value = "") Or (Range("C" & i + 1).Value = ""))) Then
            If Range("B" & i).Value = "" Then
                Range("B" & i).Value = Range("B" & i + 1).Value
            ElseIf Range("B" & i + 1).Value = "" Then
                Range("B" & i + 1).Value = Range("B" & i).Value
            End If
            If Range("C" & i).Value = "" Then
                Range("C" & i).Value = Range("C" & i + 1).Value
            ElseIf Range("C" & i + 1).Value = "" Then
                Range("C" & i + 1).Value = Range("C" & i).Value
            End If
        End If
        Range("B" & i).EntireRow.Delete Shift:=(xlUp)
        LastRow = LastRow - 1
    Next i
End Sub

Answer 3

这是另一种方法。创建人员对象。每个Personnel对象都可以有多个属性（原始表中的非空白列条目）。

通过使用集合对象的Key属性，并使用Name（column1数据）作为键，我们可以检测重复项而无需对原始数据进行排序。每个名称的属性数量仅受工作表大小的限制。

插入一个类对象并重命名它cPersonnel
