Arthur asks “Hi, I've got to believe there's a way to keep the row of column heading
always visible on the screen as I scroll down through many deeper rows
and row 1 disappears.
I know I can print a new page always with a header row, but I'm just
concerned about having it visible on the screen while viewing rows too
deep to show row 1 headers (or may even column headers on row 5, etc.).”

Sure, for example, select B2, go to Window | Freeze Panes.
Now, scroll to the right, then scroll down, see what happens…
