<p>Hi i am Chaithanya, i need to know how to hide a specific cell in a table which is empty. I have used two datasets to access the specific data from the table and joined these datasets together using joined dataset by using full outer join. But in my result i can see first only my first dataset result will be displaed and the other columns od 2nd dataset is empty and then the vice versa. I have tried using visibility also but it din work out so can any1 help me in this? to avoid the empty space for further picture i have attached the screenshot of my report.</p>
