我试图在nested_form gem的帮助下在rails中实现嵌套表单。我希望嵌套字段以表格格式显示。任何人都可以帮助我吗？
以下是我的观看文件：
<%= nested_form_for @invoice,url: invoices_path,method: :post do |f| %>
<div class="row form-inline">
<div class="col-lg-12">
<ul id="sortable" class="append-table">

<div class="th">Name</div>
<div class="th">Description</div>
<div class="th">Quantity</div>
<div class="th">Item Price</div>
<div class="th">Total Price</div>
<div class="th">Taxable</div>
<div class="th"></div>
<div class="th"></div>
</div>
<div class="table-body ui-sortable">

此结构在表结构外添加嵌套字段。如何在<div class="table-body">内添加？
