Comparing two sets of data

Hello
I have done a code for you. rest you can do it by yourself.I have used loops, perhaps someone have much easier thing to do. secondly, your tables are not of same diemnsion, the last col of table 2 will always be different. this code only colors table 1 items , for table 2 you can opy code and modify the variables

Option Explicit
 Sub remove_duplicate()
 Application.ScreenUpdating = False
 Dim arr1() As Variant
 Dim comarr() As Variant
 Dim list1 As Variant
 Dim complist As Variant
 Dim TheRange As Range
 Dim i, j, k, l, m, n, o, p, q, r, s As Long
 Dim upper As Long
 Dim StartTime As Double
  
 
 
 
ReDim arr1(17 To 21, 4 To 8)
ReDim comarr(17 To 21, 11 To 16)


 
 For j = 17 To 21
    For k = 4 To 8
        arr1(j, k) = Cells(j, k).Value
        
        
    Next
 Next
 
  
 For j = 17 To 21
    For k = 11 To 16
        comarr(j, k) = Cells(j, k).Value
       
    Next
 Next
 
 r = 5
 s = 12
 
 For l = 18 To 21
 
        If arr1(l, 4) <> comarr(l, 11) Then
                  
                     Range(Cells(l, 4), Cells(l, 8)).Select
                        With Selection.Interior
                        .Pattern = xlSolid
                        .PatternColorIndex = xlAutomatic
                        .Color = 255
                        .TintAndShade = 0
                        .PatternTintAndShade = 0
                        End With
        Else
         
         For q = 18 To 21
         
            For m = r To 8
                    
               For n = s To 15
               
                    If arr1(q, m) <> comarr(q, n) Then
                    
                       Cells(q, m).Select
                        With Selection.Interior

                       r = r + 1
                       s = s + 1
                Exit For
                        
                Else
                  
                        r = r + 1
                        s = s + 1
                Exit For
                End If

Hi Shaukat

I was stuck with the coding even though I had the logic ready. Your code did give me an idea of how to proceed. Working on it now. Will keep you posted about the progress.

Anyway thank you so much for taking the pains.
