Newlines in a table

[justanotheranonymoususer]

Consider this input:

<table>
<tr><td>Cell 1</td><td>Cell 2</td></tr>
<tr><td>Cell 3</td><td>
    <div>Cell 4-1</div>
    <div>Cell 4-2</div>
</td></tr>
</table>

Current output is:

|  |  |
| --- | --- |
| Cell 1 | Cell 2 |
| Cell 3 | Cell 4-1  Cell 4-2 |

I'd like to get:

|  |  |
| --- | --- |
|Cell 1 | Cell 2 |
|Cell 3 | Cell 4-1<br>Cell 4-2 |

Rendered in GitHub as:

Cell 1	Cell 2
Cell 3	Cell 4-1 Cell 4-2

Since <br> isn't standard markdown, make it optional, but provide a way of doing it. I tried using convert_td hook but it seems to already get the text without the newline.

This issue also causes bulleted lists to get flattened into a single line.

Example:

echo "<table> <tr> <th>Header</th> </tr> <tr> <td> <ul> <li>Item one</li> <li>Item two</li> </ul> </td> </tr> </table>" | markdownify 

| Header |
| --- |
| * Item one * Item two |
