I have problem with border-radius. For example:

<table style="border-collapse: separate; border-spacing: 2px;">
    <tbody>
        <tr>
            <td style="border: 1px dotted black; border-radius: 5px;">Name</td>
            <td style="border: 1px dotted black; border-radius: 5px;">lastname</td>
        </tr>
        <tr>
            <td style="border: 1px dotted black; border-radius: 5px;">Name</td>
            <td style="border: 1px dotted black; border-radius: 5px;">lastname</td>
        </tr>
</tbody>

In the browser I get the result I need:
