VBA在两列中删除重复项

Question

I want to use VBA to remove duplicates in two columns B and CEg when B1=B2 AND C1=C2, then B2 AND C2 data should be removed. But when B1!=B2 AND C1=C2, B2 AND C2 should not be removed as B2 has different value from B1. Right now I'm using the below code, but it does not do the right thing as I want..it removes the duplicate data in column C only.

Sub ()

Dim rCell As Range

With Worksheets("Sheet1")
  For Each rCell In Range("B1:C20") 
  rCell.EntireColumn.RemoveDuplicates 1
  Next rCell
End With

End Sub

Anyone knows how to change the code to make it work properly?

Thanks in advance!

i got you homie....

Sub RemoveDups_Copy(sSheet As String)
Dim vArray As Variant
Dim x As Long, y As Integer
Dim sTest As String

Worksheets(sSheet).Select
x = 1
Do While Cells(x + 1, 1) <> ""
x = x + 1
Loop

lastRow = x
If lastRow = 1 Then lastRow = 2
lastColumn = Cells(1, Columns.Count).End(xlToLeft).Column

ReDim vArray(1 To lastRow, 1 To lastColumn)
Set dRemove = CreateObject("Scripting.Dictionary")
Set dRemoveIndex = CreateObject("Scripting.Dictionary")


For x = 2 To lastRow
    sTest = ""
    For y = 1 To lastColumn
        sTest = sTest & "|" & Cells(x, y).Text
    Next y
    If dRemove(sTest) = "Remove" Then dRemoveIndex(x) = "Remove"
    dRemove(sTest) = "Remove"
Next x

i = 0
For x = 1 To lastRow
    If dRemoveIndex(x) <> "Remove" Then
        i = i + 1
        For y = 1 To lastColumn
            vArray(i, y) = Cells(x, y).Text
        Next y
    End If
Next x

Range(Cells(2, 1), Cells(lastRow, lastColumn)).ClearContents
Call RemoveDups_Paste(1, 1, vArray)

End Sub

Sub RemoveDups_Paste(x As Integer, y As Integer, Arr As Variant)
    Set Rng = Range(Cells(x, y), Cells(UBound(Arr, 1) - LBound(Arr, 1) + x, UBound(Arr, 2) - LBound(Arr, 2) + y))
    Rng.Resize(UBound(Arr, 1) - LBound(Arr, 1) + 1, UBound(Arr, 2) - LBound(Arr, 2) + 1) = Arr
End Sub

This records all the original (or non-dup'd) data into an array, clears the data then pastes it over as a range instead of individually. Should run fast.
