When you work with a very long table, it will be divided into several pages. You can make adjustments to the table so that the table headings appear on each page.
Repeated table headings are visible only in Print Layout view or when you print the document.
Select the heading row or rows. The selection must include the first row of the table.
Under Table Tools, on the Layout tab, in the Data group, click Repeat Header Rows.
Note: Microsoft Office 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.
