I have requirement to split the single cell into two columns, in which i need to add different search result data.

I need a table view like this, and 2 will be the value without duplicates, 5 can be the value with duplicates. need to make a dashboard like this table

This may be possible, if you create the table yourself inside an HTML panel, and make the results appear within the panel. However, that's an extraordinary level of work, only to create a table that combines headers without explaining both columns beneath it. This would be a negative practice from a visualization standpoint. I wouldn't recommend it.

If I may, perhaps what you are really doing in that table header is:
operation | Germany - distinct | Germany total | Spain - distinct | Spain total | London - distinct | London total

If you want to save horizontal header cell space, you could abbreviate the countries maybe.
operation | DE - distinct | DE total | ES - distinct | ES total | GB - distinct | GB total
