This is very embarrassing and I apologize ahead of time.

I did something yesterday, and I cannot undo whatever it is that I did.

My database always displayed with the number of the book in the first column, followed by the standard title, authors, date, size in megabytes, rating etc. In the remaining columns. These columns are displaying perfectly. But I have lost my (leftmost) number column.

My wife and I are just getting over Covid so my mental agility has decreased slightly.

Could someone please tell me how to restore the number column to the leftmost column in the database display?

I did a search, but could not find this information.
I know I am doing something stupid, but I am just not getting it.

Thank you so much for taking the time to read this.
