How do I create tables *with* headers in rich editor?

Operating system

Linux

Joplin version

2.13.8

What issue do you have?

Just as it says on the tin. I want to make tables with headers from within the rich editor, as pressing the table button creates a table with the header "hidden," so to speak. The only way I can fix this is by opening the side-by-side editor, which then completely eliminates the styling the rich editor adds to the table.

This worked once, but either there is a regression or it was reverted intentionally. I might dig a bit if I have some free time.
