Phase D.12: Table header row repeat on page break

[loadfix]

Add ability to mark table rows as header rows that repeat on each page. Upstream python-openxml#322 (18 comments).

API Design

• row.is_header = True — marks the row as a header row
• row.is_header — read the current state
• Only works on the first N consecutive rows (Word limitation)

XML

w:trPr > w:tblHeader (presence = True, absence = False)

Implementation

Simple: add/remove the w:tblHeader element on w:trPr.

Files

• src/docx/table.py — add is_header property to _Row
• src/docx/oxml/table.py — add tblHeader handling to CT_TrPr

Upstream issue: python-openxml#322
