Hello.

As title says, for example, if I run cargo run - --enable-tables with the following as input:

| A | table    |
| ------ | ---- |
| not   |  in  |
| a     | list|

* A blockquote:
  > inside a list item
* A Heading:
  # inside a list item
* A table:

  | inside | a       |
  | ------ | ------- |
  | list   | item    |
  | with   | leading |
  | empty  | lines   |
* A table:
  | inside  | a       |
  | ------- | ------- |
  | list    | item    |
  | without | leading |
  | empty   | lines   |

I'd expect the output to be ¹:

A	table
not	in
a	list

• A blockquote:

  inside a list item

• A Heading:

  inside a list item

• A table:

  inside	a
  list	item
  with	leading
  empty	lines

• A table:

  inside	a
  list	item
  without	leading
  empty	lines

But the actual output is:

A	table
not	in
a	list

• A blockquote:

  inside a list item

• A Heading:

  inside a list item

• A table:

  inside	a
  list	item
  with	leading
  empty	lines

• A table: | inside | a | | ------- | ------- | | list | item | | without | leading | | empty | lines |

<table><thead><tr><th>A</th><th>table</th></tr></thead><tbody>
<tr><td>not</td><td>in</td></tr>
<tr><td>a</td><td>list</td></tr>
</tbody></table>
<ul>
<li>
<p>A blockquote:</p>
<blockquote>
<p>inside a list item</p>
</blockquote>
</li>
<li>
<p>A Heading:</p>
<h1>inside a list item</h1>
</li>
<li>
<p>A table:</p>
<table><thead><tr><th>inside</th><th>a</th></tr></thead><tbody>
<tr><td>list</td><td>item</td></tr>
<tr><td>with</td><td>leading</td></tr>
<tr><td>empty</td><td>lines</td></tr>
</tbody></table>
</li>
<li>
<p>A table:
| inside  | a       |
| ------- | ------- |
| list    | item    |
| without | leading |
| empty   | lines   |</p>
</li>
</ul>

As the above shows:

• Table extension is enabled (hence the first table above is rendered).
• Generally, block elements inside list items are rendered exactly as what they would be in other places, no matter if there are leading empty lines. The CommonMark dingus also works this way (hence the blockquote and h1 above is rendered).
• However, unlike other block elements, pulldown-cmark interprets tables inside list items without leading empty lines as paragraphs, not tables.
