Vba Excel宏：如果列匹配，则合并行

vba excel

Vba Excel宏：如果列匹配，则合并行,vba,excel,Vba,Excel,我希望能够合并第一列中的值与之匹配的行，以便将非空白单元格的值合并为一行。例如： Mary Smith, A, [blank cell] Mary Smith, [blank cell], B Mary Smith, A, [blank cell] Mary Smith, [blank cell], B --> 我已尝试使用以下代码： Dim RowNum As Long, LastRow As Long Application.ScreenUpdating = False RowN

我希望能够合并第一列中的值与之匹配的行，以便将非空白单元格的值合并为一行。例如：

Mary Smith, A, [blank cell]

Mary Smith, [blank cell], B

Mary Smith, A, [blank cell]

Mary Smith, [blank cell], 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

这在整合数据方面做得很好，因此第一列中只有唯一的值，但是，当复制行时，空白单元格的值会复制到填充的单元格上，这不是我想要的。例如，在上述数据上运行此宏将产生：

如果您能深入了解我如何修改上述代码（或使用更优雅的代码），我们将不胜感激

试试下面的代码

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

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

这将一次完成所有13列

它也不关心A列中的值重复了多少次。该列中可能有4个

s。它将获取每列中的第一个值并使用它

之前：

之后：

这里是另一种方法。创建一个人员对象。每个人员对象可以有多个属性（原始表中的非空列条目）
通过使用集合对象的Key属性，并使用名称（column1数据）作为键，我们可以检测重复项，而不必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
