thanks for your fast reply
it looks like the below tow tables

1      3      8     11    
1      6      9     12      

1      3      8     11    
1      6      5     12  

Above is two table, which has 4 column and 2 row, respectively. the difference between two table is 9 in up table and 5 in down table.
The real table is very large. How to find the difference in the two large table ?

Please explain why "the difference between two table is 9 in up table and 5 in down table".

When you say "The real table is very large" do you mean that there are more rows? More columns?

OK try this macro. It assumes the following:

The two tables are on different sheets
The two tables are the same size and the same position
Cell A1 is in the table.

Sub ShowDifferences()
Dim cel As Range

For Each cel In Sheets("Sheet1").Range("A1").CurrentRegion
    If cel.Value <> Sheets("Sheet2").Range(cel.Address) Then
        cel.Font.Bold = True
        Sheets("Sheet2").Range(cel.Address).Font.Bold = True
    End If
End Sub

Open in new window

Approach 1: Use Conditional Formatting to highlight cells that are different from the other table.
1. Select all the cells in one of the tables
2. Create Conditional Formatting using a formula criteria like:
=A1<>A54              where A1 and A54 are the top left cells in the two tables
3. Choose a highlight color

Approach 2: Create an auxiliary column with a formula that compares one row with another
1. Create an auxiliary column to the right of the first table
2. Put a formula like the following in it:
=SUMPRODUCT(--(A1:Z1<>A54:Z54))         where A1 and A54 are the top left cells in the two tables and column Z is the rightmost column with data
3. Copy the above formula down. The easy way to do this is to doubleclick the little square at bottom right of the selection marquee surrounding the cell with the formula.
4, If you want to see just the table rows that have differences, then AutoFilter the auxiliary column and look for any value except 0

Thank you. If I just want to compare two column( or two row) difference, do you think there is simpler way to do that ?

Using my code, change line 4 to For Each cel In Selection then select the row(s) or column(s) you want to compare on Sheet1 and run the macro.

Just in case you need them, here are instructions on how to install and use the macro.

In Excel, Press Alt+F11 to open the Visual Basic Editor (VBE)

Right-click on your workbook name in the "Project-VBAProject" pane (at the top left corner of the editor window). If you don’t see an existing module then select Insert -> Module from the context menu. Otherwise just select the module.

Copy the macro (you can use the ‘Select All’ button if you like) and paste it into the right-hand pane of the VBA editor ("Module1" window)

Press Alt+F11 again to go back to Excel

Optionally, press Alt+F8 to open the "Macro" dialog window. Select the macro, click ‘Options…’,  hold down the Shift key and type the letter A (or any other letter) and click ‘OK’. Then anytime you want to run the macro press Ctrl+Shift+A.

When you close the workbook you will need to save it as an xlsm or xls file if it’s not already one of those.
