嵌套HTML表格的匹配表格高度 [英] Matching table height for nested HTML tables
问题描述
我正在尝试在一个表行中嵌套表，同时保持单个表的外观，如下面的示例所示(一个具有一行带有数据值的表和两个嵌套表的表，一个为2x2，另一个为嵌套表)3x3):
I am trying to nest tables within a table row, while maintaining the appearance of a single table, as shown in the example below (a table with a single row with a data value and two nested tables, one 2x2 and the other 3x3) :
这只是一个例子；实际的表具有更多的行和列.我之所以要使用表格，是因为可以自然地重排列宽和行高来适应表格数据，而不必担心容器大小(即表格宽度= 100％).
This is just an example; the actual table has significantly more rows and columns. I want to use tables because of the natural reflowing of column widths and row heights to fit the table data without having to worry about the container size (i.e. table width = 100%).
我遇到的问题是，最高的桌子设置了行的高度，但是其他桌子却没有展开以填充该高度，因此内部边框不会从顶部延伸到底部，如结果所示片段:
The problem I am having is that the tallest table sets the row height, but the other tables don't expand to fill that height, so the internal borders don't stretch from top to bottom as shown in the result of this snippet:
.display {
border-collapse: collapse;
}
.display, .display td, .display th {
border: 1px solid black;
}
.subtable {
border-collapse: collapse;
}
.subtable td {
border-top: 0;
border-bottom: 1px solid black;
border-left: 0;
border-right: 1px solid black;
}
.subtable tr td:last-of-type {
border-top: 0;
border-bottom: 1px solid black;
border-left: 0;
border-right: 0;
}
.subtable tr:last-of-type td {
border-top: 0;
border-bottom: 0;
border-left: 0;
border-right: 1px solid black;
}
.subtable tr:last-of-type td:last-of-type {
border: 0;
}
td {
padding: 5px;
}
td.d-subtable {
padding: 0;
}<table class="display" cellpadding="0">
<tr><th>Customer</th><th>Items</th><th>Payments</th></tr>
<tr><td>Customer Name</td>
<td class="d-subtable"><table class="subtable" cellpadding="0"><tr><td>Item1</td><td>5</td><td>$400.00</td></tr><tr><td>Item2</td><td>10</td><td>$200.00</td></tr><tr><td>Item3</td><td>2</td><td>$500.00</td></tr></table></td>
<td class="d-subtable"><table class="subtable" cellpadding="0"><tr><td>12 Sep 2018</td><td>$3,000.00</td></tr><tr><td>18 Sep 2018</td><td>$2,000.00</td></tr></table></td>
</tr>
</table>
现在，我知道我可以使用rowspan解决此问题(这就是我当前正在解决的问题)，但是这需要预先确定要对齐的行，并且可能导致出现以下代码段所产生的问题，如果将 rowspan ="2" 应用于具有两行的表格的第一行(而不是最后一行)，显然会更好:
Now I know I can resolve this problem using rowspan (and that is how I am currently solving the problem) but that requires deciding in advance which rows to line up and that can lead to issues such as that generated by the below snippet, where it would clearly be better if I'd applied rowspan="2" to the first row (instead of the last row) of the table with 2 rows:
td {
border: 1px solid black;
}
table {
border-collapse: collapse;
width: 500px;
}<table cellpadding="5">
<tr><td rowspan="3">x</td>
<td>problem when you have some really long text in the first row</td><td>p</td><td>a</td><td>b</td><td>c</td></tr><tr><td rowspan="2">z</td><td rowspan="2">q</td><td>d</td><td>e</td><td>f</td></tr><tr><td>g</td><td>some other really long text</td><td>i</td>
</tr>
</table>
我希望上面的表格看起来像这样:
I would prefer the above table to look like this:
有没有一种方法可以使用HTML/CSS来实现?表中有很多行，因此我更希望浏览器在渲染之前对其进行排序.但是，如果不可能，我可以使用Javascript/JQuery解决方案.
Is there a way to achieve what I want using HTML/CSS? There are a lot of rows in the table so I'd prefer the browser sort it out before rendering. However if it's not possible I'm open to a Javascript/JQuery solution.
更新
尽管我当时确实找到了一个可行的解决方案(请参阅我发布的答案)，但此后我遇到了一些情况，由于无法预期所有的变化，很难预先设置列的宽度(甚至是百分比).可能显示的数据.因此，我希望找到一个不依赖于此的答案.
Although I did find a workable solution at the time (see my posted answer) I have since encountered some situations where setting the widths of the columns in advance (even as percentages) was difficult owing to not being able to anticipate all the possible data to be displayed. So I'm hoping to find an answer that doesn't rely on doing that.
由于我没有像应该说的那样清晰明了，因此我想在其中嵌套表格的多个行，同时保持高度和列宽的匹配.例如，对于两行，我希望能够创建这样的布局:
Since I didn't make it as clear as I should have, I have multiple rows in which I want to nest tables, keeping the heights matched as well as the column widths. For example, for two rows, I would like to be able to create a layout like this:
原始表格HTML的结果如下:
Where with raw table HTML the result looks like this:
.display {
border-collapse: collapse;
}
.display, .display td, .display th {
border: 1px solid black;
}
.subtable {
border-collapse: collapse;
}
.subtable td {
border-top: 0;
border-bottom: 1px solid black;
border-left: 0;
border-right: 1px solid black;
}
.subtable tr td:last-of-type {
border-top: 0;
border-bottom: 1px solid black;
border-left: 0;
border-right: 0;
}
.subtable tr:last-of-type td {
border-top: 0;
border-bottom: 0;
border-left: 0;
border-right: 1px solid black;
}
.subtable tr:last-of-type td:last-of-type {
border: 0;
}
td {
padding: 5px;
}
td.d-subtable {
padding: 0;
}<table class="display" cellpadding="0">
<tr><th>Customer</th><th>Items</th><th>Payments</th></tr>
<tr><td>Customer 1</td>
<td class="d-subtable"><table class="subtable" cellpadding="0"><tr><td>Item1</td><td>5</td><td>$400.00</td></tr><tr><td>Item2</td><td>100</td><td>$20.00</td></tr><tr><td>Item3</td><td>2</td><td>$500.00</td></tr></table></td>
<td class="d-subtable"><table class="subtable" cellpadding="0"><tr><td>12 Sep 2018</td><td>$3,000.00</td></tr><tr><td>18 Sep 2018</td><td>$2,000.00</td></tr></table></td>
</tr>
<tr><td>Customer 304</td>
<td class="d-subtable"><table class="subtable" cellpadding="0"><tr><td>Item4</td><td>5</td><td>$6.00</td></tr></table></td>
<td class="d-subtable"><table class="subtable" cellpadding="0"><tr><td>20 Sep 2018</td><td>$4.00</td></tr><tr><td>27 Sep 2018</td><td>$26.00</td></tr></table></td>

</table>推荐答案
我建议使用flex来满足您的需求.Flex对于这种布局非常强大，因为我们可以轻松地让内容对其进行指导.请查看随附的代码段.它完全由HTML和CSS制成.不需要固定大小，也不需要Javascript.
I would suggest the use of flex to achieve your need. Flex is very powerful for this kind of layout as we can easily let the content guide it. Please, see the attached snippet. It is purely made from HTML and CSS. No fixed sizes and no Javascript required.

</div> 更新:已根据您的评论/答案进行了更改.它在某种程度上取决于您的HTML结构.我必须将标题移至其自己的" .row.row-item "，因此需要设置弹性基础以对齐列.可以使用多个" .row.row-item "进行扩展.请参见下面的代码段.
Update: Changed according to your comment/answer. It somewhat depends on your HTML structure. I had to move the headings to its own ".row.row-item" and therefor needed to set a flex-basis to align the columns. This can be extended with multiple ".row.row-item". See snippet below.
