handlebars.js呈现空数组的空行

Question

js，除了数组为空外，每件事都很好用。我尝试使用if else，但如果数组为空，手柄仍然会呈现一个空行。

{{#each invoice_id.invoice_services}}                       
    <tr class="uk-table-middle">
        <td>
            <span class="uk-text-large">{{ service_name }}</span><br/>
            <span class="uk-text-muted uk-text-small">{{ service_description }}</span>
        </td>
        <td>
            {{ service_rate }}
        </td>
        <td class="uk-text-center">
            {{ service_hours }}
        </td>
        <td class="uk-text-center">
            {{ service_vat }}
        </td>
        <td class="uk-text-center">
           {{ service_total }}
        </td>
    </tr>                                                 
{{/each}}
