Dear sir,

I really appreciate that you did the tool of converting MathML to PDF, but
when I tried to convert MathML to pdf found problem in the following:

<mml:math>
    <mml:mtable columnlines="solid" rowlines="solid">
        <mml:mtr>
            <mml:mtd>
                <mml:mn>1</mml:mn>
            </mml:mtd>
            <mml:mtd>
                <mml:mn>2</mml:mn>
            </mml:mtd>
        </mml:mtr>
        <mml:mtr>
            <mml:mtd>
                <mml:mn>3</mml:mn>
            </mml:mtd>
            <mml:mtd>
                <mml:mn>4</mml:mn>
            </mml:mtd>
        </mml:mtr>
    </mml:mtable>
</mml:math>

the column line and row line is vanished in pdf. I think you didn't insert
this case.

Thanks
