I am currently designing a report in iReport and want to export it in excel (xls). Here is the screen shot of what I want to design and the second screen is what I am getting.
Here is what I have managed to get. As you can see there are many problems in the output.
Here is the source to what I have done so far:

Every single time I had problems with that it was because the fields weren't properly aligned. So make sure the fields that should be vertically aligned have the same x value and have the same widths.
Your first Data field is located at x=1 (the other fields on that column are at x=0). Maybe this alone won't solve all the problems, but I am pretty sure the first Data will start to appear in the Excel output.
