Align identical data in two columns while preservi

问题:

I have a large amount of data spread throughout 3 columns on a worksheet in excel. I want to match identical values in columns A & B while keeping values associated with column B inline with their respective B components. Here is an example:

What I have-

    A   B   C
1   a   g   '
2   b   h   *
3   c   a   ?
4   d   e   $
5   e   b   /
6   f   j   )
7   g   c   #
8   h   d   @
9   i
10  j

What I am looking to achieve:

    A   B   C
1   a   a   ?
2   b   b   /
3   c   c   #
4   d   d   @
5   e   e   $
6   f
7   g   g   '
8   h   h   *
9   i
10  j   j   )

I found this code, but it doesn't also carry over the 3rd column values.

Sub Macro1()
    Dim rng1 As Range
    Set rng1 = Range([a1], Cells(Rows.Count, "A").End(xlUp))
    rng1.Offset(0, 1).Columns.Insert
    With rng1.Offset(0, 1)
        .FormulaR1C1 = _
        "=IF(ISNA(MATCH(RC[-1],C[1],0)),"""",INDEX(C[1],MATCH(RC[-1],C[1],0)))"
        .Value = .Value
    End With
End Sub

Any help would be greatly appreciated! Thanks

You will have to store the values in memory (a variant array seems appropriate), then clear the values and work through A1:A10 looking for matches to the first rank of the array.

Sub aaMacro1()
    Dim i As Long, j As Long, lr As Long, vVALs As Variant
    With ActiveSheet
        lr = .Cells(Rows.Count, 1).End(xlUp).Row
        vVALs = Range("B1:C" & lr)
        Range("B1:C" & lr).ClearContents
        For i = 1 To lr
            For j = 1 To UBound(vVALs, 1)
                If vVALs(j, 1) = .Cells(i, 1).Value Then
                    .Cells(i, 2).Resize(1, 2) = Application.Index(vVALs, j)
                    Exit For
                End If
            Next j
        Next i
    End With
End Sub

It would probably be best if you tested that on a copy of your data as it does remove the values from B1:C10 before returning them.
