What is the difference between the file header and a customized header?

File Header
The file header is located immediately above the variable headers at the top of the spreadsheet window. You can use this header to include a summary title or other identification of the data file (or results). Double-click in the header area (or press F2) to edit or enter information.

To select the header only (for formatting) click once in the upper-left corner (the mouse pointer is an outlined plus sign ). Press CTRL+ENTER or ALT+ENTER to enter a new line (note that you need to extend the height of the field to see new lines that you are adding). For more information on the spreadsheet window, see the Multimedia Table Window Overview.

In addition to adding new lines to the file header, Statistica Spreadsheets (and all other Statistica documents) can easily be annotated by entering notes into the Comments area of the Document Properties dialog box (on the Summary tab). To access the Document Properties dialog box: Ribbon bar - select the File tab; in the left pane, click Properties. Classic menus -  on the File menu, select Properties. The Comments area can hold any type of comments or supplementary information.

Customized Header
A customized header is used when printing spreadsheets (or other Statistica documents, example, reports, graphs). This header can include a title, page numbers, time of printing, date, the name of the file, and any custom text you might want to include. To create a header, select Header/Footer from the View tab or menu. For more information, see the Modify Header/Footer topic. Note that while the file header is associated only with spreadsheets, any printed Statistica document can have a customized header.
