Impossible to force headers on tables

Reproduction steps

1. Edit a page with Blocknote editor
2. Insert a table
3. Observe the table in view and edit mode

Expected

The table is displayed the same in view and edit modes.

Actual

The page is displayed without a header row in edit mode, and with a header row in view mode.

Notes

In Markdown, the header row is not optional but Blocknote does not have an option to force tables to have a header.
