Table conversion fails for tables without headers and cells that contain <p>'s

[PORTB]

Cells that contain <p>

Input:

<table>
    <thead>
        <tr>
            <th>Heading 1</th>
            <th>Heading 2</th>
            <th>Heading 3</th>
        </tr>
    </thead>
    <tbody>
    <tr>
        <td>Table cell</td>
        <td>Table cell</td>
        <td>Table cell</td>
        <td>Table cell</td>
    </tr>
    <tr>
        <td>Table cell</td>
        <td>
            <p>p #1</p>
            <p>p #2</p>
        </td>
        <td>Table cell</td>
        <td>Table cell</td>
    </tr>
    </tbody>
</table>

Output:

| Heading 1 | Heading 2 | Heading 3 |
| --- | --- | --- |
| Table cell | Table cell | Table cell | Table cell |
| Table cell |

p #1

p #2  | Table cell | Table cell |

Preferred output:

| Heading 1 | Heading 2 | Heading 3 |
| --- | --- | --- |
| Table cell | Table cell | Table cell | Table cell |
| Table cell | p #1 <br> p #2  | Table cell | Table cell |

or even just removing the line break entirely

Seems related to #7

Tables without a header

Input:

<table>
    <tbody>
    <tr>
        <td>Table cell</td>
        <td>Table cell</td>
        <td>Table cell</td>
        <td>Table cell</td>
    </tr>
    <tr>
        <td>Table cell</td>
        <td>Table cell</td>
        <td>Table cell</td>
        <td>Table cell</td>
    </tr>
    </tbody>
</table>

Output (does not show as a table at all):

| Table cell | Table cell | Table cell | Table cell |
| Table cell | Table cell | Table cell | Table cell |

Preferred output:
Add a blank header to the table

| Table cell | Table cell | Table cell | Table cell |
| Table cell | Table cell | Table cell | Table cell |
