我有一个 HTML 表,我想要最后一行,不包括带有 class 的行.table-bottom,并删除它border-bottom

<table cellpadding="0" cellspacing="0" style="width:752px;" class="table">
    <tr class="table-top"><th style="width:40px;">ID</th> <th>Post title</th> <th>Date</th> <th>Owner</th> <th style="width:100px;">Actions</th></tr>
    <tr class="table-middle"><td>1</td> <td>Test</td> <td>16.7.2013</td> <td>Admin</td> <td>Delete</td></tr>
    <tr class="table-middle"><td>2</td> <td>Test 2</td> <td>3.8.2013</td> <td>Admin</td> <td>Delete</td></tr>
    <tr class="table-bottom"><td colspan="5"></td></tr>
</table>
.table tr th {
color:#929191;
font-weight:bold;
font-size:14px;
text-align:left;
padding-left:19px;
border-right:1px solid #d7d7d7;
border-bottom:1px solid #d7d7d7;
}
.table tr th:last-child {
border-right:none;
}
.table tr td {
color:#929191;
font-weight:bold;
font-size:12px;
padding:19px;
border-right:1px solid #d7d7d7;
border-bottom:1px solid #d7d7d7;
}
.table tr td:last-child {
border-right:none;
}
.table .table-middle:last-of-type td {
border-bottom:none;
background:red;
}
.table tr.table-middle td:first-child {
text-align:center;
}
.table tr th:first-child {
text-align:center;
padding-left:0px;
}
.table tr.table-bottom td {
border-right:none;
border-bottom:none;
}

但是.table .table-middle:last-of-type td选择器不起作用。

有任何想法吗?

简短的回答:你不能用 CSS 来做,除非你改变你的 HTML 结构。

更多详情:

:last-of-type伪类,表示在其父元素的子元素列表中是其类型的最后一个兄弟元素的元素。

考虑这个选择器:.table-middle:last-of-type.

虽然.table-middle正确指向元素,但具有.table-middle类的元素不是它的最后一个兄弟type,因为术语type指的是 HTML 元素本身,而不是element.class.


这是工作解决方案:

HTML

<table cellpadding="0" cellspacing="0" style="width:752px;" class="table">
    <thead>
        <tr>
            <th style="width:40px;">ID</th>
            <th>Post title</th>
            <th>Date</th>
            <th>Owner</th>
            <th style="width:100px;">Actions</th>
        </tr>
    </thead>
    <tfoot>
        <tr>
            <td colspan="5"></td>
        </tr>
    </tfoot>
    <tbody>
        <tr>
            <td>1</td>
            <td>Test</td>
            <td>16.7.2013</td>
            <td>Admin</td>
            <td>Delete</td>
        </tr>
        <tr>
            <td>2</td>
            <td>Test 2</td>
            <td>3.8.2013</td>
            <td>Admin</td>
            <td>Delete</td>
        </tr>        
    </tbody>
</table>

CSS

.table tbody tr:last-child td {
    border-bottom:none;
    background:red;
}

你可以在不使用类的情况下让它变得更简单:

HTML:

<table>
    <tr>
        <td>...</td>
        <td>...</td>
        <td>...</td>
        <td>...</td>
        <td>...</td>
    </tr>
    <tr>
        <td>...</td>
        <td>...</td>
        <td>...</td>
        <td>...</td>
        <td>...</td>
    </tr>
    <tr>
        <td>...</td>
        <td>...</td>
        <td>...</td>
        <td>...</td>
        <td>...</td>
    </tr>
    <tr>
        <td>...</td>
        <td>...</td>
        <td>...</td>
        <td>...</td>
        <td>...</td>
    </tr>
</table>

CSS:

table {
    width: 500px;
}
table td {  /* style for all the cells between the top and bottom row */
    background: red;
}
table tr:first-child td { /* style for the cells in the top row */
    background: green;
}
table tr:last-child td { /* style for the cells in the bottom row */
    background: blue;
}
table tr:first-child td:first-child, /* first row, first cell */
table tr:first-child td:last-child, /* first row, last cell */
table tr:last-child td:first-child, /* last row, first cell */
table tr:last-child td:last-child { /* last row, last cell */
    background: yellow;
}
