Word Tables: Repeat the Header Row on Every Page

When a lengthy table in Microsoft Word extends to a second page, subsequent readers encounter rows of figures and names without column headers. To remedy this, simply click the table's top row, navigate to the Table Layout tab, and activate the header row repeat feature. In desktop Word, this option is labeled "Repeat Header Rows."

The repeated header will then appear at the top of the table on every following page, and any edits made to the header will automatically propagate to subsequent pages, as it is the same row displayed again rather than separate copies. This can be achieved by right-clicking the header row, selecting Table Properties, opening the Row tab, and checking the option to repeat the header at the top of each page.

A common error is attempting to repeat a row that is not the first one in the table, as Word only permits repeating the initial row(s). Another pitfall is inserting a manual page break inside the table, which causes Word to split it into two separate tables, resulting in the header not following the page break. Although copying the header row onto the next page manually appears adequate, it becomes problematic if additional rows are added later, causing the copied header to appear in the middle of page two.

In Python-docx, there is no direct property for this functionality, but the setting is represented by a single XML flag on the row. To implement this in a script, you can use the following code snippet: from docx.oxml import OxmlElement from docx.oxml.ns import qn tr_pr = table.rows[0]._tr.get_or_add_trPr() flag = OxmlElement("w:tblHeader") flag.set(qn("w:val"), true) tr_pr.append(flag) This approach ensures that long tables in reports maintain consistent headers, preventing the inconvenience experienced on page two.
