Jquery库symfony集合不适用于<table>元素

Question

当我在自定义表单主题中添加元素时，集合的增量不起作用！

我使用这个库：https://github.com/ninsuo/symfony-collection

{% block PriceType_row %} 
    {{ form_widget(form) }} 
{% endblock %} 

{% block PriceType_widget %} 
    <tr> 
     <td> 
      {{ form_widget(form.quantityFrom, {'attr': {'class': 'form-control'}}) }} 
     </td> 
     <td> 
      {{ form_widget(form.quantityTo, {'attr': {'class': 'form-control'}}) }} 
     </td> 
     <td> 
      {{ form_widget(form.bestUnitPrice, {'attr': {'class': 'form-control'}}) }} 
    </td> 
    <td> 
     {{ form_widget(form.getPaid, {'attr': {'class': 'form-control'}}) }} 
    </td> 
    <td> 
     {{ form_widget(form.vatRate, {'attr': {'class': 'form-control'}}) }} 
    </td> 
</tr> 
{% endblock %} 

{% block ProductType_widget %} 
    {{ form_widget(form.prices) }}l 
{% endblock %} 

感谢您的帮助！ :)

我musted添加elements_selector到我的集合JavaScript，

$('.collection-prices').collection({ 
    elements_selector: '> tr', 
});
