Currently i am using the defined template for maintaining our data.

For example, above mentioned screenshot is the Initial Template (DataXLFile.xlsx).
After processing some calculation, updating the values in the same template ((DataXLFile.xlsx).

When printing the excel in the same template, we have to Highlight the difference of the value in every cell if anything changes before and after calculation.

Also I have "n" number of columns to fulfill the requirement in both table. (anyhow both columns are same).
In some cases with this requirement, I just want to exclude some columns.
for example, i just want to exclude some of the columns like "M", "AA","CA",. (because, these are not required to highlight the columns)
How to exclude the columns while printing in excel.
pls. let me know if you need any more details.
