How can CSS3 be used to style tables in PHP forms for better design?

To style tables in PHP forms using CSS3 for better design, you can utilize CSS properties like border-collapse, border-spacing, padding, and background-color to enhance the visual appearance of the table. By applying CSS styles to the table elements generated by PHP, you can create a more visually appealing and user-friendly form layout.

echo '<style>
    table {
        border-collapse: collapse;
        width: 100%;
    }
    th, td {
        padding: 8px;
        text-align: left;
        border-bottom: 1px solid #ddd;
    }
    th {
        background-color: #f2f2f2;
    }
</style>';

echo '<table>
    <tr>
        <th>Header 1</th>
        <th>Header 2</th>
    </tr>
    <tr>
        <td>Data 1</td>
        <td>Data 2</td>
    </tr>
</table>';
