Add empty paragraph at the end of the editor

[zgrybus]

Good morning,
I have one simple question. What should I do so that after adding any field, an empty paragraph always appears at the end?
Exactly the same as it is done at https://milkdown.dev/playground
I ask because when I add a table, I can't add any text because there is no paragraph there.
