Your question has already been answered in the other thread you've opened. We kindly ask you to use just one support channel to contact us. Posting the same questions numerous times slows down our response time because we will need to review and address two tickets instead of one. Moreover threads are handled according to license and time of posting, so if it is an urgent problem, we suggest you use a support ticket, which would be handled before a forum thread. Anyway here is our reply:
"If all you want is to show / hide some spacing between the groups of a table according to a specific condition, you can accomplish this quite easily by adding an empty row at the bottom of the table and applying a filter condition to the corresponding row group. The only tricky moment here is that you cannot apply a filter to a static group, so you need to make the table group dynamic first, by applying a constant grouping expression to it. To illustrate this approach better, I have created a small sample report that allows you to show / hide a blank row between the table groups according to the value of a report parameter. The attached archive file contains the sample report and a short movie that shows how the report is made. This sample requires the Q1 2010 release of Telerik Reporting to run, so we recommend you to upgrade, if you have not done so already."
