Creating/deleting number column for a table ***not a "new field"***

[ChristopherTalbot]

Searched pretty extensively with no result... how can a numerical column be added to a table in ArcPro? I do not mean adding a field but a column on the left hand side with sequential numbers for each row. Thank you in advance

Sincerely, 

Christopher

It can't, the table appearance is controlled by the software and its presentation and construction is not open for modification

Thank you and fair enough, just seems weird though since nearly everything in arc pro is customizable...
