当我运行此代码时，数据从我正在拉出的表格中正确地输入到表格单元格中，但是表格重叠，因此它们在表格下方显示表格，它们也向左移动对。我还包含了我的CSS代码，我尝试在循环开始后在它周围添加一个div包装器，以便它可以放在每个itteration的包装器中，但这还没有解决问题。
<% if @form.valid? %>
<div id="display">
<% if @form.items.any? %>
<% @form.items.each do |w| %>
<% if !w.hours.any? %>

我不确定我是否正确理解了您的问题，但是在模板中间您有2个成员行而没有设置colspans。这部分：
<tr>
<td class="tg-datacell">e</td>
<td class="tg-datacell"></td>
</tr>
<tr>
<td class="tg-datacell">b</td>
<td class="tg-datacell"></td>
</tr>
<tr>
<td class="tg-datacell">c</td>
<td class="tg-datacell"></td>
</tr>
编辑：还有一件事是将 放入空的tds中。空tds可以崩溃
