我有一个对象数组，这些对象是 <tr>和 child 一起 <td>的等如何将对象放入 dom 中，替换它们在我的方法之前的内容？

<table id="trg">
    <tbody>
        <tr class="trg-quantity-head">
            <th class="trg-quantity quantity-head">Quantity</th>
            <th class="trg-quantity">0-10</th>
            <th class="trg-quantity">11+</th>
            <th class="trg-quantity">100+</th>
            <th class="trg-quantity">250+</th>
        </tr>
