查找某个值的列中的所有重复项，并从下一列返回值

Question

我正在尝试做一些看起来像这样的东西：

在右侧的表格中，所有的唯一记录都将存储在某个区域中。但是，某些记录可能存在于更多区域，并且可以从 A 列和 B 列中的列表中获取此信息。宏应获取 D 列中的每个唯一记录并在 A 列中搜索它，每次找到它时，应该复制 B 列中的位置/区域并粘贴到表中唯一记录的旁边。我想我可以通过循环来做到这一点，但是我在下面的代码中创建的内容并没有真正起作用。

第二个挑战是让它明白，在一个位置已经复制到表中，新找到的位置需要粘贴到同一条唯一记录的下一个空闲单元格中。

我知道我的代码有点吓人，但即使只是关于我应该看哪个方向的建议，我也很感激......提前致谢！

    Dim UC As Variant, UCrng As Range, ra As Range

    Set UCrng = Range("F2:F6")

    For Each UC In UCrng

        Set ra = Cells.Find(What:=UC, LookIn:=xlFormulas, _
        LookAt:=xlPart, SearchOrder:=xlByColumns, SearchDirection:=xlNext, _
        MatchCase:=False, SearchFormat:=False).Activate

        ra.Offset(0, 1).Copy Destination:=Range("E2")

    Next

End Sub

Answer 1

我建议遍历所有行（A + B 列），例如：

For i = 1 to Rows.Count
'DoStuff
Next i

对于每一行，如果 A 的值不存在，则将其复制到 D 中。 您可以像这样访问这些值：

Cells(i, "A").Value
Cells(i, "B").Value

用于查找列中的值，see here。如果您发现重复项，请使用另一个循环来检查您的特定行中的哪一列（E、F、G、..）是第一个空列，并且超过了那里 B 列的值。

试试看：

Option Explicit

Sub test()

    Dim LastRowA As Long, LastRowD As Long, i As Long, rngColumn As Long
    Dim rng As Range

    With ThisWorkbook.Worksheets("Sheet1")

        LastRowD = .Cells(.Rows.Count, "D").End(xlUp).Row

        .Range("D2:J" & LastRowD).ClearContents

        LastRowA = .Cells(.Rows.Count, "A").End(xlUp).Row

        For i = 2 To LastRowA

            LastRowD = .Cells(.Rows.Count, "D").End(xlUp).Row

            Set rng = .Range("D1:D" & LastRowD).Find(.Range("A" & i).Value, LookIn:=xlValues, lookat:=xlWhole)

            If Not rng Is Nothing Then
                rngColumn = .Cells(rng.Row, .Columns.Count).End(xlToLeft).Column
                Cells(rng.Row, rngColumn + 1).Value = .Range("B" & i).Value
            Else
                .Range("D" & LastRowD + 1).Value = .Range("A" & i).Value
                .Range("E" & LastRowD + 1).Value = .Range("B" & i).Value
            End If

        Next i

    End With

End Sub

我认为这段代码会做你想做的事。请尝试一下。
