我有一个ember hbs组件，其中我们有表，其中td的值应该根据前一个td的值来决定，这是我的hbs代码，请帮助？

<div class="row">
                            <div class="col-md-12">
                                {{#if model.novs}}
                                    <table class="table table-striped">
                                        <thead>
                                            <tr>
                                                <th>Notice#</th>
                                                <th>Type</th>
                                                <th>Violation</th>
                                                <th>Inspection Item</th>
                                                <th>

                                                </th>
                                            </tr>

                                        <div class="well text-center no-margin">

                                {{/if}}
                            </div>
                        </div>

在上面的代码中，model.result.items有Violation元素，我如何才能显示novv.ViolationNumber的诺维.itemNum，请提供帮助-提前感谢。
