是的。我用它们动态地隐藏/显示一个表的相关部分，例如一个课程。 即。

<table>
  <tbody id="day1" style="display:none">
    <tr><td>session1</td><tr>
    <tr><td>session2</td><tr>
  </tbody>
  <tbody id="day2">
    <tr><td>session3</td><tr>
    <tr><td>session4</td><tr>
  </tbody>
  <tbody id="day3" style="display:none">
    <tr><td>session5</td><tr>
    <tr><td>session6</td><tr>
  </tbody>
</table>

可以提供一个按钮来在所有内容之间切换，或者通过操作tbody来切换当前日期，而不需要单独处理许多行。

Martin Joiner的问题是由对<caption>标签的误解引起的。

<caption>标记定义了一个表标题。

<caption>标签必须是<table>标签的第一个子标签。

每个表只能指定一个标题。

另外，注意scope属性应该放在<th>元素上，而不是<tr>元素上。

写一个多头多体表的正确方法应该是这样的:

<table id="dinner_table"> <caption>This is the only correct place to put a caption.</caption> <tbody> <tr class="header"> <th colspan="2" scope="col">First Half of Table (British Dinner)</th> </tr> <tr> <th scope="row">1</th> <td>Fish</td> </tr> <tr> <th scope="row">2</th> <td>Chips</td> </tr> <tr> <th scope="row">3</th> <td>Peas</td> </tr> <tr> <th scope="row">4</th> <td>Gravy</td> </tr> </tbody> <tbody> <tr class="header"> <th colspan="2" scope="col">Second Half of Table (Italian Dinner)</th> </tr> <tr> <th scope="row">5</th> <td>Pizza</td> </tr> <tr> <th scope="row">6</th> <td>Salad</td> </tr> <tr> <th scope="row">7</th> <td>Oil</td> </tr> <tr> <th scope="row">8</th> <td>Bread</td> </tr> </tbody> </table>

我已经创建了一个JSFiddle，其中有两个嵌套的ng-repeat表，父ng-repeat在tbody上。如果检查表中的任何一行，您将看到有六个tbody元素，即父级。

    </div>

( Side note: This fills up the DOM if you have a lot of data on both levels, so I am therefore working on a directive to fetch data and replace, i.e. adding into DOM when clicking parent and removing when another is clicked or same parent again. To get the kind of behavior you find on Prisjakt.nu, if you scroll down to the computers listed and click on the row (not the links). If you do that and inspect elements you will see that a tr is added and then removed if parent is clicked again or another. )

是的。来自DTD

<!ELEMENT table
     (caption?, (col*|colgroup*), thead?, tfoot?, (tbody+|tr+))>

所以它需要一个或多个。它接着说

规则时使用多个tbody节 组与组之间是否需要表 行。

编辑:标题标签属于表，因此应该只存在一次。不要像我这样把每个tbody元素都关联一个标题:

<table>
    <caption>First Half of Table (British Dinner)</caption>
    <tbody>
        <tr><th>1</th><td>Fish</td></tr>
        <tr><th>2</th><td>Chips</td></tr>
        <tr><th>3</th><td>Pease</td></tr>
        <tr><th>4</th><td>Gravy</td></tr>
    </tbody>
    <caption>Second Half of Table (Italian Dinner)</caption>
    <tbody>
        <tr><th>5</th><td>Pizza</td></tr>
        <tr><th>6</th><td>Salad</td></tr>
        <tr><th>7</th><td>Oil</td></tr>
        <tr><th>8</th><td>Bread</td></tr>
    </tbody>
</table>

上面的坏例子:不要复制

上面的示例并没有像您期望的那样呈现，因为这样写表明误解了标题标签。你需要大量的CSS技巧来使它正确呈现，因为你将违背标准。

我在标题标签上搜索了w3c标准，但没有找到明确规定每个表只能有一个标题元素的规则，但事实就是如此。

根据规范中的这个例子，可以这样做:w3-struct-tables。

表行可以分别使用THEAD、TFOOT和TBODY元素被分组为表头、表脚和一个或多个表体部分。
