Hi thank you for your advice.
It must be difficult for you without consulting the file.
But please see the attached image
1. It seems that controls are correctly hidden (May is ruled out), but the border of each row is not hidden.
2. My file does not contain container table. It only has 1 repeating table.
3. I set row heights to auto but I still get this...
If you can think of anything else, please let me know...
