Hi Tim, thanks so much for your help!
I would like to add a border style to the table in mashup. That unused space will hide the right border style.
I have to remove that unused space to show the right border style.
Could you please tell me how to remove that unused space in Qlik sense desktop?
Unfortunately Qlik Sense does not let you change the borders on ANY of the standard objects within the dashboard.
The next best thing is to use the simple table extension and manually edit the html/css to get the borders: Simple Table Extension. This link will show you the code for the extension. You can use the Dev Hub to create a table with whatever style you want and use it throughout your applications.
