When you work with a very long table, it must be divided where a page break occurs. You can make adjustments to the table to make sure than the information appears as you want it to when the table spans multiple pages.
Repeated table headings are visible only in print layout view or when you print the document.
Note Microsoft Word automatically repeats table headings on new pages that result from automatic page breaks. Word does not repeat a heading if you insert a manual page break within a table.
