Is the Sticky Table Header Feature No Longer Available on Confluence Server?

[Michael Furlan]

Around five years ago, the sticky table header feature was available on Confluence Server without the use of a macro. As I recall, this feature was enabled unless the table:  

• Was inside a page layout, or inside another table.
• Had no header row.
• Had a header column instead of a header row.
• Contained another table that had its own header row. 

Is this feature no longer available without a table macro? Thanks.
