Table permission management issues

[Xipro]

I have deployed owncloud and onlyoffice myself, and other functions are normal. However, when using multiple people to share document editing tables, when setting editing permissions for a certain area for others, it can be configured successfully. However, when the person given editing permissions enters the document and clicks on a cell, it displays that editing is not allowed for this range. When I use onlyoffice's test example, I can achieve the function of managing document permissions by region, but when using owncloud to connect to the editor, the associated users cannot be correctly given editable permissions.

This is the information I found on the official website

This is the document owner granting user permissions to editable areas

This is the editing status of X * * * n user on H11

This is the error message when X * * n users are editing on H11
