Hide header row when empty (table without header)

[Spenhouet]

Markdown doesn't officially support tables without header. A common workaround is to simply make a header with empty cells.

|        |        |
| :----- | :----- |
| Cell 1 | Cell 2 |

GitHub also only partially supports this use-case, as GitHub will still show the header but smaller:

Cell 1	Cell 2

Milkdown displays the table header in full height:

Even though GitHub doesn't support it, I wish that Milkdown could just completely hide the header when it is empty i.e. support tables without header. If that's not wanted, than I wish that the header is also displayed with a small height as done by GitHub.
