Hi,

Have not the setting to prevent this for now. But you can open the files below and remove the content, then the user have no way to change anything of the table by the table properties dialog.

\CuteSoft_Client\CuteEditor\Dialogs\Tag\tag_inserttable.ascx 

\CuteSoft_Client\CuteEditor\Dialogs\Tag\tag_table.ascx 

Regards,

Ken
