View products that this article applies to.

This article describes update 4011039 for Microsoft Word 2016 that was released on September 5, 2017. This update has a prerequisite.

Known issues in this update

After you install this update 4011039, you may encounter the following issues:

  • If you merge vertical cells in a table, the cell content disappears, and you can't select the merged cell.

  • If you open an existing document that has a table with merged cells, the cells are displayed as blank.

These issues occur only for those who receive Microsoft Office 2016 updates by using the Windows Installer (MSI) technology. If you have a Click-to-Run edition of Office, such as Office 365 Personal, you won't encounter these issues.


As a workaround, you can uninstall this update, and your tables will return to normal. We anticipate releasing the fix for these issues in the next monthly update that's tentatively scheduled for October 3, 2017. For more information, see the following Microsoft article :

To fix this issue, install October 3, 2017, update for Word 2016 (KB4011140).
