Hello all,
As I can't find a solution to my problem, I post my request hoping that an expert among you will help me solve my problem.

Presentation of my worksheet: The worksheet is named: "Issus", it has 11 columns and many (many) rows whose length varies each month, I have reduced the length of the worksheet for the needs of submitting my application.

Here is an overview of the "Issues" sheet:

The Macros request that I present to you will be made in 3 different macros, these 3 Macros are similar because they do almost the same job:

First Macro: In the "Issue" sheet, I want to group all the rows including the content of the cell of the 2nd column (Column "B") and at the same time that of the cell of the 3rd column (Column "C") are identical with the cells of the following rows to the same columns.

Unless I am mistaken, here is the desired result:

Second Macros: In the same sheet ("Issue"), I want to group all the rows whose contents of the cells of the 2nd column (Column "B") are identical with the cells of the following rows to the same column.

Third Macros: Still in the same "Issue" sheet, I want to group all the rows whose contents of the cells of the third column (Column "C") are identical with the cells of the following rows in the same column.

As my "Issus" sheet is large (Length large) and so that the search does not take long, can you (Please) use (if possible) a dictionary combined with tables to speed up the processing , gender :
For i = 2 TB UBound(tablo, 1).

I add that it would also be desirable (for more visibility) to insert an empty line between each group of data (See the presentation of the desired result.

I remain at your disposal for any additional information.
Cheers.

Hi @harzer, thanks for posting on the forum.

You want the macro to run on the same sheet, I guess you want view 1, 2 or 3 with just running a macro.

So if you want First Macro run Macro1, if you want Second macro run Macro2 and if you want Third macro run Macro3.
The 3 macros execute the MacroAll that receives the view number you want to see.

Then put all of the following code in a module:
VBA Code: 
Sub Macro1()      'columns B and C
  Call MacroAll(1)
End Sub

Sub Macro2()      'columns B
  Call MacroAll(2)
End Sub

Sub Macro3()      'columns C
  Call MacroAll(3)
End Sub

Sub MacroAll(n)
  Dim sh As Worksheet
  Dim dic As Object
  Dim a As Variant, b As Variant, ky As Variant
  Dim i As Long, j As Long, k As Long, y As Long
  Dim nRow As Long, nCol As Long, filA As Long
  Dim kya As String
 
  Set sh = Sheets("Issus")
  Set dic = CreateObject("Scripting.Dictionary")
  a = sh.Range("A2:K" & sh.Range("B" & Rows.Count).End(3).Row).Value
  ReDim b(1 To UBound(a, 1) * 2, 1 To UBound(a, 1))
  ReDim c(1 To UBound(a, 1) * 2, 1 To UBound(a, 2))
 
  For i = 1 To UBound(a, 1)
    If a(i, 2) <> "" Then
      Select Case n
        Case 1: kya = a(i, 2) & "|" & a(i, 3)
        Case 2: kya = a(i, 2)
        Case 3: kya = a(i, 3)
      End Select
      If Not dic.exists(kya) Then
        y = y + 1
        b(y, 1) = i
        dic(kya) = y & "|" & 1
      Else
        nRow = Split(dic(kya), "|")(0)
        nCol = Split(dic(kya), "|")(1)
        nCol = nCol + 1
        b(nRow, nCol) = i
        dic(kya) = nRow & "|" & nCol
      End If
    End If
  Next
 
  For Each ky In dic.keys
    nRow = Split(dic(ky), "|")(0)
    nCol = Split(dic(ky), "|")(1)
    For i = 1 To nCol
      k = k + 1
      filA = b(nRow, i)
      For j = 1 To UBound(a, 2)
        c(k, j) = a(filA, j)
      Next
    Next
    k = k + 1
  Next
 
  sh.Range("A2").Resize(UBound(c, 1), UBound(c, 2)).Value = c
  Set dic = Nothing
  Set sh = Nothing
  Erase a, b, c
End Sub

Hello DanteAmor,
Thank you for your proposal, it is exactly what I expected, the code is perfect and gives me the desired result.
Thanks again for sharing your knowledge. Congratulations to you.

Hello Dante Amor,
Can you show me the code that adds a blank line between each group.
I tried to decipher your code but given my level, I have difficulties to do so, unless you will be kind enough to comment on your code. Big THANKS to you.

Hello Hazer.
With pleasure I explain the operation of the macro.​

In this line:​
Rich (BB code): 
    Next
    'This increment in counter k is to leave an empty row.
    k = k + 1
  Next

Hello Dante Amor,
Thank you for the comments, the code is beautifully written, the comments help me a lot to understand, especially they show me all the steps to solve the problem, without these comments, impossible for me to see the progress of the code. Thanks again.
