I have not come across any way to add a 'line number' to list tables in SAS Visual Analytics. if this have been solved or previously suggested, please feel free to delete this Idea.
if it has not, it would be nice to have a check box in the Options for the list table object (and maybe in a cross tab object) to add 'line nubmers:
This would be rather useful for consumers who take screen shots of tables to more easily highlight or call attention to information contained within their tables.
