Hide table border in footer

In the call to action part of the footer I've put the following code, but as you can see in the screen print the borders of the table are still showing. What should I do to make them disappear?

<table border="none">

<tbody>

<tr>

<td colspan="4"><h4>Unseren Service</h4></td>

<td colspan="2"><img src="/wp-content/uploads/2021/02//transparent.png" alt="transparant" width="32" height="32"></td>

<td colspan="6"><h4>Unsere Zielgruppe</h4></td>

<td colspan="2"><img src="/wp-content/uploads/2021/02//transparent.png" alt="transparant" width="32" height="32"></td>

<td colspan="4"><h4>Leider!</h4></td>

</tr>
