Table summarizing totals

[fabridp]

Hello.

I'm building a table report. I grouped this table by the field X and in the group footer I made totals.

PRICE GROUP

100      1

200      1

TOTAL 300

100     2

TOTAL 100

______________________________________________________________________________________

Now, i want make something different like this:

PRICE GROUP

100      1

200      1

100     2

 

 

TOTALS TABLE

GROUP TOTAL

1             300

2             100

________________________________________________________________________________________

How can I do that with Jasper-iReport considering i want to output a list of element PRICE/TOTALS?

___________________________________________________________________________

DOCUMENT 1

PRICE GROUP

100      1

200      1

100     2

 

TOTALS TABLE

GROUP TOTAL

1             300

2             100

 

DOCUMENT2

 

PRICE GROUP

100      1

100      1

200     2

 

TOTALS TABLE

GROUP TOTAL

1             200

2             200

.....

Thanks in advance.
