[英]Delete entire row if the same value is found in another cell on the same row
首先，我必须提到我正在使用Excel for Mac ，因此任何代码建议都需要适用于使用 Office 365 的 Mac 。
我有一个包含九列名称的大型数据集。 如果同一行的多个列中有相同的名称，我想删除整行
示例数据集：
所以所有这些行都将被删除，因为：
Jason在第1行出现twiceJason在第2行出现3次Jason在第3行出现4次Sam在第4行出现twiceFred在第5行出现3次因此，无论名称在同一行数据中重复多少次，我都想删除该整行。
我的代码如下。 此代码有效，但它与大型数据集崩溃。 我知道必须有一种更快、更有效的方法来编写此代码，以便它可以处理大型数据集。 另外，我的代码太重复了。 必须有一种方法可以使代码更简单。 无论如何，这是代码。

假设您的数据如下所示
代码
Option Explicit
Sub Sample()
Dim ws As Worksheet
Dim Ar As Variant
Dim lRow As Long, lCol As Long
Dim i As Long, j As Long, k As Long, l As Long
'~~> Set this to the relevant sheet
Set ws = Sheet1
With ws
If Application.WorksheetFunction.CountA(.Cells) = 0 Then Exit Sub
'~~> Find last row and column
lRow = .Cells.Find(What:="*", _
After:=.Range("A1"), _
Lookat:=xlPart, _
LookIn:=xlFormulas, _
SearchOrder:=xlByRows, _
SearchDirection:=xlPrevious, _
MatchCase:=False).Row
lCol = .Cells.Find(What:="*", _
After:=.Range("A1"), _
Lookat:=xlPart, _
LookIn:=xlFormulas, _
SearchOrder:=xlByColumns, _
SearchDirection:=xlPrevious, _
MatchCase:=False).Column
'~~> Get the data into an array
Ar = .Range(.Cells(1, 1), .Cells(lRow, lCol))
End With
'~~> Clear the rows in an array for the required condition
For i = LBound(Ar) To UBound(Ar)
For j = 1 To lCol
For k = 2 To lCol
'~~> An additional check to see if the compared cell is not blank
If Ar(i, j) = Ar(i, k) And Len(Trim(Ar(i, 1))) <> 0 And j <> k Then
For l = 1 To lCol: Ar(i, l) = "": Next l
Exit For
End If
Next k
Next j
Next i
Dim delRange As Range
With ws
'~~> Clear data for output
.Cells.Clear
'~~> Get the data back in the worksheet
.Range("A1").Resize(lRow, lCol).Value = Ar
If Application.WorksheetFunction.CountA(.Cells) = 0 Then Exit Sub
'~~> Find the new last row
lRow = .Cells.Find(What:="*", _
After:=.Range("A1"), _
Lookat:=xlPart, _
LookIn:=xlFormulas, _
SearchOrder:=xlByRows, _
SearchDirection:=xlPrevious, _
MatchCase:=False).Row
'~~> Check for blank rows
For i = 1 To lRow
If Application.WorksheetFunction.CountA(.Range(.Cells(i, 1), .Cells(i, lCol))) = 0 Then
If delRange Is Nothing Then
Set delRange = .Rows(i)
Else
Set delRange = Union(delRange, .Rows(i))
End If
End If
Next i
'~~> If blank rows found then delete them in one go
If Not delRange Is Nothing Then delRange.Delete shift:=xlUp
End With
End Sub
在行动
通过一点研究，我发现下面的 function 将删除同一单元格中的重复项。
Function RemoveDupeWords(text As String, Optional delimiter As String = " ") As String
Dim dictionary As Object
Dim x, part
Set dictionary = CreateObject("Scripting.Dictionary")
dictionary.CompareMode = vbTextCompare
For Each x In Split(text, delimiter)
part = Trim(x)
If part <> "" And Not dictionary.Exists(part) Then
dictionary.Add part, Nothing
End If
Next
If dictionary.Count > 0 Then
RemoveDupeWords = Join(dictionary.keys, delimiter)
Else
RemoveDupeWords = ""
End If
Set dictionary = Nothing
End Function
将此 function 作为公式应用在您需要解决方案的范围内。
RemoveDupeWords(text, [delimiter])
在哪里：
文本（必需）- 要从中删除重复文本的字符串或单元格。 分隔符（可选）- 分隔重复文本的分隔符。 如果省略，则使用空格作为分隔符。 function 不区分大小写，这意味着小写和大写字母被视为相同的字符。
