Customize Spreadsheet Document Headers and Footers
To customize headers and footers of a spreadsheet document, choose the Table – Print Options – Headers and Footers menu item.
In the window that opens, you can specify which page the headers and footers will be printed from, as well as the text they will contain.
Each header or footer is conditionally divided into three parts: left, right, and center. In each part, you can enter text and specify the parameters that will be filled when printing. These parameters include: page number, number of pages, date and time of document printing.
