使用table布局，span标签放不到table中

Question

在代码中将他放到了table中，但是在控制台还是显示在body中，怎么那个span标签都放不进去

    <table>
        <tr>
            <td class="check1"><input type="checkbox" style="width: 17px; height: 17px;"></td>
            <td id="univalent">24</td>
            <td class="amount">
                <button onclick="cut1()">-</button>
                <input type="text" value="0" id="amount" style="width: 30px;">
                <button onclick="plus1()">+</button>
            </td>
            <td id="btn1"><button onclick="ll()">删除</button></td>
        </tr>
        <tr><span id="price">dada</span></tr>
        <tr>
            <td class="check2"><input type="checkbox" style="width: 17px; height: 17px;"></td>
            <td id="univalent2">22.9</td>
            <td class="amount2">
                <button onclick="cut2()">-</button>
                <input type="text" value="0" id="amount2" style="width: 30px;">
                <button onclick="plus2()">+</button>
            </td>
            <td id="btn2"><button onclick="ll()">删除</button></td>
        </tr>
       
    </table>
    

   <script>
        // 获取input节点
        var amount = document.querySelector('#amount')
        var amount2 = document.querySelector('#amount2')
        // 获取单价
        var univalent = amount.parentNode.previousElementSibling.innerHTML
        var univalent2 = amount2.parentNode.previousElementSibling.innerHTML
        // 获取 input节点的value属性值
        var sum = amount.value
        var sum2 = amount2.value
        var price = document.querySelector('#price')

        // console.log(sum2)
        function plus1() {
            sum++
            amount.value = sum
            cost()
        }

        function cut1() {
            sum--
            if (sum < 0) {
                sum = 0
                return
            }
            amount.value = sum
            cost()
        }
        function plus2() {
            sum2++
            amount2.value = sum2
            cost()
        }
        function cut2() {
            sum2--
            if (sum2 < 0) {
                sum2 = 0
                return
            }
            amount2.value = sum2  
            cost()
        }
        function ll(){
            alert('删除成功')
        }

        function cost() {
             price.innerHTML = (univalent * sum + univalent2 * sum2).toFixed(2)
        } 
    </script>

Answer 1

price的span需要放在tr>td内噢
比如

      <tr>
        <td>    
          <span id="price">dada</span>
        </td>
      </tr>

效果
