iReport - Create a calendar report with data on different dates - jasper-reports

Question

Recently I've come up to some question related to calendar report in iReport.
This is the link I referenced to create a calendar:
Sample Report to Create a Monthly Calendar
With the above reference, I created a calendar report that can display court attendance record corresponding to different dates:

This report simply generates a monthly calendar with a sub-report in each cell, where the sub-report displays the court attendance information according to each date.
The problem now is, with the fixed page height of the main report, when there's too many rows inside the sub-report and its heights overflows the page height of the main report, it automatically switches to the next column of the report. As a result the report will become malformed. I've looked for various solution for the overflow issue but none of them worked. Can someone enlighten me to have a workaround for this?
Here are some attributes that are available in Jasper that I've tried:
Position Type: Float
Report Split Type: Stretch
Include row and column attribute inside the report element from net.sf.jasperreports.export.xls.auto.fit
Setting detail band height during runtime

Answer 1

Finally turned away from Jasperreports, and I managed to switch the implementation to poi. In this case the Excel configuration could be a bit more flexible based on my needs.
Conclusion: Jasper is not quite capable in creating content included calendar!
