You may need to print the row and column headings on your page,
for example if you have been working with the spreadsheet
as an educational exercise and need to show what you have done.
To print these borders:
Display the Paper dialogue box.
Increase the size of the Column margin entry to about 8mm and the Row margin entry to around 10mm.
Click OK. The borders will then appear on the paper on screen and when you print the worksheet.
