Change and existing report

Hi All,

Ive got the attached report which pulls totals of various suppliers so it outputs like this.

Supplier Name            Total
Supplier No1               6
Supplier No2               17
Supplier No3               9
Supplier No4               4
Supplier No5               8
Supplier No6               7
Supplier No7               5


Now I want to add Previous 5 days (1 column for each day) to the right of and a grand total of all totals at the end so it would look like this

Supplier Name            1st      2nd      3rd      4th      5th      Total
Supplier No1               6         3            5         3         4          21
Supplier No2               17       5            3         8         6          39
Supplier No3               9         5            4         7         7          32
Supplier No4               4         3            5         3         4          21
Supplier No5               8         8            9         3         3          31

What do I need to do with the report to achieve this?

Thank you
