There is a very helpful line between my column headers of my custom table questions in edit mode that isn’t there when respondents answer the questions (ex: survey: Validation – Front of House). How do I make those lines between column headers render for the respondents like it does for me?
What you are seeing is the default rendering of the question via the respondent view.
To change the border color to appear the way it does on the Build page, would require custom CSS coding on your Style page.
I’ve played around with this but it’s a bit over my head. Perhaps another Community contributor might have some suggestions.
