Question

我有这个css：

    .table1 thead th:first-child{

  -webkit-border-bottom-right-radius:8px;
    -webkit-border-top-right-radius:8px;
    -moz-border-radius:8px 0px 8px 0px;
    border-bottom-right-radius:8px;
    border-top-right-radius:8px;
}
.table1 thead th:last-child{

  -webkit-border-bottom-left-radius:8px;
    -webkit-border-top-left-radius:8px;
    -moz-border-radius:0px 8px 0px 8px;
    border-bottom-left-radius:8px;
    border-top-left-radius:8px;
}

由于某种原因，最后一个孩子的边界，但第一个没有任何想法为什么？（以铬格式检查）

这是HTML：

            <th scope="col" abbr="Business">סוג משרה</th>
            <th scope="col" abbr="Deluxe">משכורת</th>
        </tr>
    </thead>
    <tbody>
        <tr>

            <td>512 MB</td>
            <td>1 GB</td>
            <td>2 GB</td>
            <td>4 GB</td>
        </tr>
        <tr>

            <td>50 GB</td>
            <td>100 GB</td>
            <td>150 GB</td>
            <td>Unlimited</td>
        </tr>
        <tr>

            <td>Unlimited</td>
            <td>Unlimited</td>
            <td>Unlimited</td>
            <td>Unlimited</td>
        </tr>
        <tr>

            <td>19.90 $</td>
            <td>12.90 $</td>
            <td>free</td>
            <td>free</td>
        </tr>

    </tbody>
</table>

正如有人提到的那样，必须要有一些东西，我已经把它全部搞定了。谁有线索？

编辑：发现了问题。 HTML中有一个空元素。
