Thanx Nicolas!
It worked like a charm! Attached is the result
*Edit
In case anyone wonders, I got the text of the product to align to the left adding this line of CSS to the style CSS:
.hikashop_product_name2 {
text-align: left !important;
}
And I changed listing_table.php to this:
<td class="hikashop_product_name_row">
<span class="hikashop_product_name2">
<?php if($this->params->get('link_to_product_page',1)){ ?>
<b><a href="<?php echo $link;?>">
<?php }
echo $this->row->product_name;
if($this->params->get('link_to_product_page',1)){ ?>
</a></b>
<?php } ?><br><br> <font size="1"><?php echo $this->row->lijstbeschrijving; ?></font>
</span>
<?php if(!empty($this->row->extraData->afterProductName)) { echo implode("\r\n",$this->row->extraData->afterProductName); } ?>
</td>
