Summary

In the new Confluence release, as mentioned here, the table headers in Confluence Cloud is supposed to stick to the top when large tables are scrolled.
PS: The sticky header will not work when the user edited the table. If user copies and pastes back the table, the sticky table will work. However, when they edited the table, the sticky table will stop working.

3. Save the page
4. Sticky table will not work.

6. Copy the table
7. Delete the table and paste the table again
