How to set the height of a cell in a table when laying out html emails?

Question

HTML

When setting cellpadding, the height of the cell increases. In this case, it becomes 292px. And not in all mailers.

<table style="table-layout:fixed;" cellspacing="0" cellpadding="20" width="250px" height="250px">
    <col width="250px">
    <tr height="250px">
        <td height="250px" width="250px" style="background:#008fc8; overflow:hidden;">Произвольный текст</td>
    </tr>
</table>
