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.
