Question details
The user is experiencing a display inconsistency where table headers repeat properly across pages in reading mode but fail to repeat in editing mode, causing the table to appear merged.
- Product
- Office Online Server 2016
- Device & OS
- not provided
- Scenario
- Editing and viewing a multi-page document with structured tables via the browser using Office Online Server.
- Observed behavior
- Table headers repeat on every new page in view mode as expected, but when switched to edit mode, the headers disappear from subsequent pages and the table appears merged across the document.
Verify that your original document is properly formatted by opening it in a desktop word processor and checking that the 'Repeat as header row at the top of each page' setting is enabled in the table properties.
Report the Rendering Issue to the Microsoft Q&A Community
Since this is a known rendering limitation specific to Office Online Server 2016's edit mode, raising the issue in the official Microsoft Q&A community is the most direct path to getting specialized engineering assistance.
Office Online Server uses a lightweight web rendering engine to ensure performance when editing documents in a browser. This engine sometimes simplifies document layouts, causing advanced features like repeating table headers to temporarily disappear until you switch back to reading or print view.
To get official insights on this specific version's rendering behavior, Microsoft engineers monitor the Office Online Server tags on their community forums.

Frequently Asked Questions
Why do table headers repeat in Word but not in Office Online Server edit mode?
Office Online Server uses a simplified HTML rendering engine for its browser-based edit mode to ensure high performance and responsiveness. This simplified view temporarily disables complex layout features, like repeating table headers, until the document is switched back to reading or print view.
Does the 'Repeat Header Rows' feature work properly in desktop word processors?
Yes, standard desktop applications fully support repeating header rows across multiple pages in all standard viewing layouts, including the default Print Layout used for editing.
Is there a setting in Office Online Server to fix the merged table appearance?
Currently, there is no built-in toggle in Office Online Server 2016 to force full print layout rendering during web-based editing. The best workaround is to utilize the 'Open in Desktop App' feature for documents that require complex table editing.
