Wrong even/odd rows in nested tables

[mccoys]

A table inside another table messes with the even/odd count of the parent table rows.

.. rst-class:: fancy

+------------------------------+
| SOME TITLE ...............   |
+------------------------------+
| +--------------------------+ |
| | Item 1                   | |
| +--------------------------+ |
| | Item 1                   | |
| +--------------------------+ |
| | Item 1                   | |
| +--------------------------+ |
+------------------------------+
| ANOTHER TITLE  ...........   |
+------------------------------+
| +--------------------------+ |
| | Item 1                   | |
| +--------------------------+ |
| | Item 1                   | |
| +--------------------------+ |
+------------------------------+

Gives this result:

<table class="fancy docutils align-default">
    <colgroup>
        <col style="width: 100%">
    </colgroup>
    <tbody>
        <tr class="row-odd"><td><p>SOME TITLE ……………</p></td><!-- This is odd -->
        </tr>
        <tr class="row-even"><td> <!-- This is even -->
            
            <table class="docutils align-default">
                <colgroup>
                    <col style="width: 100%">
                </colgroup>
                <tbody>
                    <tr class="row-odd"><td><p>Item 1</p></td>
                    </tr>
                    <tr class="row-even"><td><p>Item 1</p></td>
                    </tr>
                    <tr class="row-odd"><td><p>Item 1</p></td>
                    </tr>
                </tbody>
            </table>
            </td>
            
        </tr>
        <tr class="row-even"><td><p>ANOTHER TITLE  ………..</p></td> <!-- This is even but should be odd -->
        </tr>
        <tr class="row-odd"><td>
            
            <table class="docutils align-default">
                <colgroup>
                    <col style="width: 100%">
                </colgroup>
                <tbody>
                    <tr class="row-odd"><td><p>Item 1</p></td>
                    </tr>
                    <tr class="row-even"><td><p>Item 1</p></td>
                    </tr>
                </tbody>
            </table>
            
            </td>
        </tr>
    </tbody>
</table>

The inner table numbering has overwritten the outer table numbering.

How to Reproduce

$ git clone https://github.com/mccoys/EvenOddSphinx.git
$ cd EvenOddSphinx
$ make html

Open build/index.html and look at the table odd/even rows.

Expected behavior

Even/odd numbering of inner tables should be counted with a different variable than that of the outer table
