When editing the report, in the Data tab click on the Sum icon and uncheck the Show Total Row option. It is checked by default on every table:

If you need the total row for online viewing, you can create a different version of the report just for Datalink, and have it invisible for regular users. Do this only if absolutely necessary, as Apptio will take time calculating both versions of the report in every promotion!
I believe this will do what you want.
Good luck, @Saaraunsh Rege.
