在分组产品表中显示产品尺寸 - Magento

Question

我想在前端表中显示产品尺寸，但我不确定如何将后端的产品尺寸回显到表格中。下面是我的编码，我尝试添加大小列并写入 echo $this->getSizeHtml($_item, true) 以显示大小值，但无法工作。

<table class="table table-bordered responsive-table" id="super-product-table">
    <col />
    <col />
    <col width="1" />
    <thead>
        <tr>
            <th><?php echo $this->__('Product Name') ?></th>
            <th><?php echo $this->__('Size') ?></th>
            <?php if ($this->getCanShowProductPrice($_product)): ?>
            <th><?php echo $this->__('Price') ?></th>
            <?php endif; ?>
            <?php if ($_product->isSaleable()): ?>
            <th><?php echo $this->__('Qty') ?></th>
            <?php endif; ?>
        </tr>
    </thead>
    <tbody>
    <?php if ($_hasAssociatedProducts): ?>
    <?php foreach ($_associatedProducts as $_item): ?>
        <?php $_finalPriceInclTax = $this->helper('tax')->getPrice($_item, $_item->getFinalPrice(), true) ?>
        <tr>
            <td><?php echo $this->escapeHtml($_item->getName()) ?></td>
            <td><?php echo $this->getSizeHtml($_item, true) ?></td>
            <?php if ($this->getCanShowProductPrice($_product)): ?>
            <td>
                <?php if ($this->getCanShowProductPrice($_item)): ?>
                <?php echo $this->getPriceHtml($_item, true) ?>
                <?php echo $this->getTierPriceHtml($_item) ?>
                <?php endif; ?>
            </td>
            <?php endif; ?>
            <?php if ($_product->isSaleable()): ?>
            <td>
            <?php if ($_item->isSaleable()) : ?>
                <div class="quantity-wrapper clearfix">
                    <?php  $random = rand(5, 1500); ?>
                    <div class="quantity-decrease btn-qty" onclick="qtyDown(<?php echo $random; ?>)"><i class="meigee-arrow-left"></i></div>
                    <input type="text" id="qty_<?php echo $random; ?>" name="super_group[<?php echo $_item->getId() ?>]" maxlength="12" value="<?php echo $_item->getQty()*1 ?>" title="<?php echo Mage::helper('core')->quoteEscape($this->__('Qty')); ?>" class="form-control qty" />
                    <div class="quantity-increase btn-qty" onclick="qtyUp(<?php echo $random; ?>)"><i class="meigee-arrow-right"></i></div>
                </div>
            <?php else: ?>
                <p class="availability out-of-stock"><span><?php echo $this->__('Out of stock') ?></span></p>
            <?php endif; ?>
            </td>
            <?php endif; ?>
        </tr>
    <?php endforeach; ?>
    <?php else: ?>
       <tr>
           <td colspan="<?php if ($_product->isSaleable()): ?>4<?php else : ?>3<?php endif; ?>"><?php echo $this->__('No options of this product are available.') ?></td>
       </tr>
    <?php endif; ?>
    </tbody>
</table>

实际上，我想要如下图所示的结果表：

希望有人能指导我如何显示大小值问题。谢谢。
