Jasper report table with subtables

[Methos81]

Hello everyone.

I need help to solve my problem with jasper. Currently i have to generate a jasper report similar to the following table (values are masked for confidential reasons)

The requirement for this table is as follows:

Each row(1) can have sub rows(1.a) (row 1 and 1.a has differnet styles) Each subrows(1.a) has a sub row(1.a.1)(row 1.a and 1.a.1 has different style)

There is a posibility of multiple subrows like 1.a,1.b if there is more than one subrows then i have to sum the total and add another row (with different style)

So i need help for 3 points:

• How can i set differents styles by row type?
• How can i add the sub row with total if there are more than 1 subrow?
• How can i manage sub rows inside a row with jasper?

Thanks for the help.

• How can i set differents styles by row type?

one way would be to create a uniqueid in your sql and assign this uniqueid to the conditional expression

• How can i add the sub row with total if there are more than 1 subrow?

I can think of creating groups for each row and creating variables from the group would create subtotals.

• How can i manage sub rows inside a row with jasper?

Inside these Row groups, create table elements for Sub rows.
