Markdown in beginning of a row in a Table with no outer pipes

Hi,

Thank you for this rust-native markdown parser. It is really helpful in one of my project! Just wanted to report a bug (I believe it is a bug) when, in a table, there is markdown styling at the beginning of a row of a table without outer pipes. Here is an example:

Markdown:

Markdown | Less | Pretty
--- | --- | ---
*Still* | `renders` | **nicely**
1 | 2 | 3

GitHub: Markdown	Less	Pretty
Still	`renders`	nicely
1	2	3

GitHub renders it nicely, but markdown-rs renders one table with the rest being a paragraph text between starting from the inner markdown. (I believe this is a bug, because stackedit, dillinger and markdownpreview are rendering this nicely too)

I am using the to_mdast function and I have the following mdast structure: (positions omitted for clarity).
I am using the latest version 1.0.0-alpha.13

    children: [
        Table {
            children: [
