OK, one
more good idea, then that's enough. Here is the way to print the
Headings and the Gridlines, if you wish. This print out makes it
easy to proof the formulas in the hard copy.
Try
This: Edit the Page Layout
Open
Formulas and Functions.xlsx.
Go to Page Layout.
Find the Sheet Options.
Select: Print.
Go to Office -> Print.
Select: Print Preview.

What Do You See? The Print Preview should show
the gridlines and the headers just as you would see the spreadsheet
on the screen.
