Hide the "Data sheet" tab if there is no data for Presta 1.7

[markovo]

Hello!

I want to hide the "Data sheet" tab (where the product features are displayed) when there are no features selected. Here is the code from my template:

{block name='product_features'}
    {if $product.grouped_features}
        <section class="product-features">
            <dl class="data-sheet">
                {foreach from=$product.grouped_features item=feature}
                    <dt class="name">{$feature.name}</dt>
                    <dd class="value">{$feature.value|escape:'htmlall'|nl2br nofilter}</dd>
                {/foreach}
            </dl>
        </section>
    {/if}
{/block}

What should I add to this code, so the "Data sheet" tab is hidden when there is no features selected for the product.
