For instance, I just want to show the row highlighted in green below. Is that possible?
Create a filter that specifies what values to INCLUDE (Session Medium = Print, etc.) Then add that filter to your table.
If you want to highlight a value or row, use conditional formatting https://support.google.com/looker-studio/answer/9528890?hl=en#what-you-can-format
