Thanks a ton for the solution. It worked, however my data source is not spreadsheet and in fact bigdata table which is live in connection.
I am afraid I cannot duplicate the data and also not getting a union to do so. Is there any other way to achieve this?
Creating "Table view" is not the strength of Tableau at all, and answer is "no" unfortunately as long as I know.
Except another Very troublesome way to create ton of different worksheets and merge on dashboard.
