Is there a way to add a header row to a draw.io table after the table's been drawn and populated?

I created a table in draw.io for Confluence. I now saw that you can insert a table with a header row if you press the space key while inserting it. I did not do that in the first place, but I would like to have the header row for my table now. Is there a way to accomplish that?

Yes, you can also add a header row to your table after the table has been created. Just click on the table once. You’ll now see an orange diamond at the top middle of the table. Click and hold your mouse button on the orange diamond to pull down the header cell. For more options on tables in draw.io, check out our Youtube playlist on tables (https://drawio.link/tables).
