Nest tables with Office Javascript API in Word

Question

I want to nest a table object inside other table cell using the javascript office api.

I saw that the TableCell object doesn't have the method insertTable so i cannot call it though the cell. The table's method insertTable can receive only the "Before" and "After" locations - so the new one will be inserted just before or after the parent table.

I've manage to nest table though HTML by using this code:

body.insertHtml('
<table border="1">
<tr>
<td>Cell1</td><td>Cell2</td>
</tr>
<tr>
<td>
    <table border=3 color=black>
    <tr><td>10</td><td>20</td><td>30</td></tr</table>
    </td>
<td>Cell 4</td>
</tr>
</table>', Word.InsertLocation.start);

Is there a way to nest a table with the javacript API?

Thanks!
