TCPDF中的嵌套表高度

Is it possible to make nested table fit height of its parent cell in TCPDF?

My code:

<?php
require_once('tcpdf/config/lang/eng.php');
require_once('tcpdf/tcpdf.php');

$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);

$pdf->setPrintHeader(false);
$pdf->setPrintFooter(false);

$pdf->SetFont('times', 'BI', 8);

$pdf->AddPage();

$pdf->writeHTML('<table>
    <tr><td bgcolor="gray"> Angoisse et vif espoir, sans humeur factieuse.<br/>
Plus allait se vidant le fatal sablier,<br/>
Plus ma torture était âpre et délicieuse;<br/>
Tout mon coeur s’arrachait au monde familier</td>
    <td bgcolor="lightgray">Second</td>
    <td bgcolor="gray">Third</td>
    <td>
        <table style="height: 100%">
            <tr bgcolor="blue" style="height: 30%"><td bgcolor="yellow" style="height: 30%">Ichi</td></tr>
            <tr bgcolor="white" style="height: 30%"><td bgcolor="cyan" style="height: 30%">Ni</td></tr>
            <tr bgcolor="blue" style="height: 30%"><td bgcolor="yellow" style="height: 30%">San</td></tr>
        </table>
    </td></tr>
</table>');

$pdf->Output('example_002.pdf', 'I');
?>

I want table in last cell to fill it entirely. Is there any way to do this?

Well, it seems the only way is not to use WriteHTML, but to write table as sequence of cells.
