thymeleaf的写法和EL表达式的写法是有些类似的，总的说thymeleaf的写法更好：

 <td th:text="${#dates.format(i.startdate,'yyyy-MM-dd')}"></td>

<tr th:each="i:${list}">
            <td th:text="${i.id}"></td>
            <td th:text="${i.projectname}"></td>
            <td th:text="${#dates.format(i.startdate,'yyyy-MM-dd')}"></td>
            <td th:text="${#dates.format(i.enddate,'yyyy-MM-dd')}">
            </td>
            <td th:if="${i.status eq 1}">已申报</td>
            <td th:if="${i.status eq 2}">审核中</td>
            <td th:if="${i.status eq 3}">已审核</td>

            <td th:if="${i.status ne 3}">
                <a th:href="@{'getOne/'+${i.id}}">审核</a>
            </td>
            <td th:if="${i.status eq 3}">已审核</td>
        </tr>
