How to add sub totals on table or matrix visualisation

[Anonymous]

Hello everybody, 

Im trying to create a visualisation able to show the Sub total per seller, with different dates.

On my data table looks like that:

And i would like to have a visualisation ( a table or a matrix ) that shows the sub-totals per seller, as follows:

If i used a table, i cant have the subtotals by seller, and when i try to use a matrix, i think i have a problem with the aggregation of the dates ( i dont need to agregate dates)  and the subtotals doesn't appears.
Do you know how i can achieve this?

@Anonymous , In matrix visual you have the option to disable subtotal using per row level . Also disable stepped layout

thanks for your answer. Im trying to add the subtotals, as the 2nd image. When i change the row subtotals it doesn't change anything on my table. Also i have only things as FIRST VALUES.
