Hi
Unfortunately, this is by design, and the space between the two tables is to distinguish between different tables.
I tried a variety of methods to change this situation, such as embedding these three tables into one table at the same time. After exporting to CSV format, although there are no extra blank lines between the tables, the regular "," separators are displayed on different lines. You can also try to see if it is the same as my question. Even though I have completed many settings in rsreportserver.config, this comma cannot be removed. To be honest, your needs may not be met.
Best Regards,
Joy
