Insert table inside single product page

Hey noventa90,
Thank you for the link to your site, I recommend moving the woocommerce tabs below the product image so they will be full width and your table will show full width.
Before:

After:

This could be achieved on all product pages with this code added to the end of your child theme functions.php file in Appearance ▸ Editor:

function av_woo_tabs_below() {
    remove_action('woocommerce_after_single_product_summary', 'woocommerce_output_product_data_tabs', 1 );
    add_action('woocommerce_after_single_product_summary', 'woocommerce_output_product_data_tabs', 20 );
    }
add_action( 'init', 'av_woo_tabs_below');

But as I understood your question you only wanted this on some products, so use this instead:

add_action( 'woocommerce_single_product_summary', 'woo_tabs_below', 20);
function woo_tabs_below() {
   global $post;
   $idsArr = [1100, 1098];
   if ( is_single() && in_array($post->ID, $idsArr )) {
      remove_action('woocommerce_after_single_product_summary', 'woocommerce_output_product_data_tabs', 1 );
    add_action('woocommerce_after_single_product_summary', 'woocommerce_output_product_data_tabs', 20 );

   }
}

change the numbers 1100, 1098 to your product pages, and you can add more.
You will notice some extra padding between the tabs and the product image so add this css to your Quick CSS to remove:

#top.single-product .template-shop .single-product-main-image {
	padding-bottom: 0;
}
#top.single-product .template-shop .single-product-main-image ~ .woocommerce-tabs {
	padding-top: 0;
}

Best regards,
Mike
