How can I set table colspan? - jasper-reports

Question

My question is that how I can set colspan value for a table footer column in iReport, in jrxml file.
I have to use iReport to create easily my PDF design. I send fields and parameters values from PHP via Tomcat. I don't use Java for create a dynamic jasper report.
That means I have to resolve my problem from jrxml.
Is it possible to make it?

Answer 1

You can't do a colspan as such but you can group the table columns in iReport (select more than 1 column in the table footer). Then remove the cells of the individual columns in the footer and add a cell for the "Group Header" in the footer.
All pure iReport/JRXML.
