MS Excel 宏删除重复的行并总结它们的值 [英] MS Excel macro deleting duplicate rows and sum their values

问题描述

我对 vba 非常熟悉，但我不知道如何修改以下脚本以使其符合我的预期.

I'm very briefly familiar with vba and I cannot work out how to amend the following script to make it do what I expect.

基本上我有 5 列 excel.A 列是我想要求和的值，前提是 B and C and D 和 E 作为一行是唯一的.

Basically I have 5 column excel. Column A are the values I would like to sum, providing that B and C and D and E are unique as a row.

我找到了以下脚本，它几乎满足了我的需求:

I found the following script, which does nearly what I need:

Option Explicit

Sub RedoDataset()
Dim LastCol As Long
Dim LastRowData As Long
Dim LastRow As Long
Dim Ctr As Long

Dim CompanyArr
Dim RowFoundArr
Dim SumArr
Dim Rng As Range
Dim SettingsArray(1 To 2) As Integer

On Error Resume Next
With Application
    SettingsArray(1) = .Calculation
    SettingsArray(2) = .ErrorCheckingOptions.BackgroundChecking
    .Calculation = xlCalculationManual
    .EnableEvents = False
    .ErrorCheckingOptions.BackgroundChecking = False
    .ScreenUpdating = False
End With
On Error GoTo 0

With ThisWorkbook
    With .Sheets("Sheet1")
        LastRowData = .Cells(Rows.Count, 1).End(xlUp).Row
        LastCol = .Cells(1, Columns.Count).End(xlToLeft).Column
        Set Rng = .Range(.Cells(1, 1), .Cells(1, LastCol))

        .Columns(2).AdvancedFilter Action:=xlFilterCopy, _
        CopyToRange:=.Cells(1, LastCol + 2), Unique:=True

        LastRow = .Cells(Rows.Count, LastCol + 2).End(xlUp).Row

        ReDim CompanyArr(1 To LastRow - 1)
        ReDim RowFoundArr(1 To LastRow - 1)
        ReDim SumArr(1 To LastRow - 1)

        For Ctr = 1 To LastRow - 1
            CompanyArr(Ctr) = .Cells(Ctr + 1, LastCol + 2)
            RowFoundArr(Ctr) = Application.Match(CompanyArr(Ctr), .Columns(2), 0)
            SumArr(Ctr) = Application.SumIf(.Columns(2), CompanyArr(Ctr), .Columns(1))
            .Cells(RowFoundArr(Ctr), 1) = SumArr(Ctr)

            Set Rng = Union(Rng, .Range(.Cells(RowFoundArr(Ctr), 1), _
            .Cells(RowFoundArr(Ctr), LastCol)))
        Next Ctr
        .Columns(LastCol + 2).Delete

        For Ctr = LastRowData To 2 Step -1
            If IsError(Application.Match(Ctr, RowFoundArr, 0)) Then
                .Rows(Ctr).Delete
            End If
        Next Ctr

    End With
End With

On Error Resume Next
With Application
    .Calculation = SettingsArray(1)
    .ErrorCheckingOptions.BackgroundChecking = SettingsArray(2)
    .EnableEvents = True
    .ScreenUpdating = True
    .ScreenUpdating = True
End With
On Error GoTo 0


End Sub

这对 A 列的值求和，使 B 列唯一.我如何扩展它以便不仅 B 是唯一的，而且条件是 - B and C and D 和 E 组合为一行是唯一的.基本上整行与其他行相比是唯一的，但不必每列只包含唯一值:

this sums values of column A leaving column B unique. How do I extend this so not only B is unique, but condition is - B and C and D and E are unique in combination as a row. Basically where the whole row is unique comparing to other, but not necessary each column contain only unique values:

    A    B      C      D      E
1  0.01  La    Ba     foo    boo
2  0.03  La    boo    foo    Ba
3  0.12  La    foo    Ba     boo
4  1.05  Ba    La     foo    boo

推荐答案

试试这个代码 - 它使用不同的方法，更灵活:

Try this code - it uses a different approach, that's more flexible:

Const cStrDelimiter As String = ";"

Sub Aggregate()
    Dim dic As Object
    Dim rng As Range
    Dim strCompound As String
    Dim varKey As Variant
    Set dic = CreateObject("Scripting.Dictionary")

    'Store all unique combinations in a dictionary
    Set rng = Worksheets("Sheet1").Range("A1")
    While rng <> ""
        strCompound = fctStrCompound(rng.Offset(, 1).Resize(, 4))
        dic(strCompound) = dic(strCompound) + rng.Value
        Set rng = rng.Offset(1)
    Wend

    'Save all unique, aggregated elements in worksheet
    Set rng = Worksheets("Sheet1").Range("G1")
    For Each varKey In dic.Keys
        rng = dic(varKey)
        rng.Offset(, 1).Resize(, 4).Cells = Split(varKey, cStrDelimiter)
        Set rng = rng.Offset(1)
    Next
End Sub

Private Function fctStrCompound(rngSource As Range) As String
    Dim strTemp As String
    Dim rng As Range
    For Each rng In rngSource.Cells
        strTemp = strTemp & rng.Value & cStrDelimiter
    Next
    fctStrCompound = Left(strTemp, Len(strTemp) - Len(cStrDelimiter))
End Function
