输出类似具有动态记录数的 rowspan 的内容
给定一个像这样的表:
Col 1 | Col 2
1 2
1 3
2 4
...第 1 列中可以是任意数量的 1、2 等。我想动态输出如下所示的内容:
<table>
<tr>
<td rowspan="2">
1
</td>
<td>
2
</td>
</tr>
<tr>
<td>
3
</td>
</tr>
<tr>
<td rowspan="1">
2
</td>
<td>
4
</td>
</tr>
</table>
我的问题是,对于上面的 html,我会计算不同 1 的数量以找到适当的行跨度数,然后返回并迭代它们以获取 html 输出。我只是想知道是否有一种更简单/更快的方法来执行类似的操作,我可以迭代记录并在第 1 列中的下一行与最后一行的第 1 行不同时添加一些内容。
我读到的内容听起来像我可以只使用 rowspan="0" 作为第一条记录,并按 tbody 标签将组分开,如下所示:
<table>
<tbody>
<tr>
<td rowspan="0">
1
</td>
<td>
2
</td>
</tr>
<tr>
<td>
3
</td>
</tr>
</tbody>
<tbody>
<tr>
<td rowspan="0">
2
</td>
<td>
4
</td>
</tr>
</tbody>
</table>
...rowspan="0" 将只跨越它所包含的 tbody 部分。我还没有能够找到很多关于此方法的信息,但我无法让它在 IE 或 Firefox 中工作。那么有什么东西可以加快我的 html 渲染速度吗?提前致谢。
Given a table like this:
Col 1 | Col 2
1 2
1 3
2 4
...and could be any number of 1's, 2's, etc. in Col 1. I want to dynamically output something that would look like this:
<table>
<tr>
<td rowspan="2">
1
</td>
<td>
2
</td>
</tr>
<tr>
<td>
3
</td>
</tr>
<tr>
<td rowspan="1">
2
</td>
<td>
4
</td>
</tr>
</table>
My issue is that, for the above html, I would have to count the number of distinct 1's to find the appropriate rowspan number, then go back and iterate through them for the html output. I was just wondering if there was an easier/quicker way to do something similar where I could just iterate through the records and add something once the next row in Col 1 is different than the last row's Col 1.
I read something that sounded like I could just use rowspan="0" for the first record, and divide the groups up by tbody tags like so:
<table>
<tbody>
<tr>
<td rowspan="0">
1
</td>
<td>
2
</td>
</tr>
<tr>
<td>
3
</td>
</tr>
</tbody>
<tbody>
<tr>
<td rowspan="0">
2
</td>
<td>
4
</td>
</tr>
</tbody>
</table>
...and the rowspan="0" would just span the tbody section it is contained in. I haven't been able to find much info on this method, and I couldn't get it to work in IE or Firefox. So is there anything along those lines that would speed up my html rendering? Thanks in advance.

像这样尝试怎么样?
至少在这张表上看起来它可以在 IE8 和 FF 3.6 中运行。我假设如果 rowspan="10" 在具有 3 行且有 2 个部分(第一行 2 行,第二行 1 行)的表上工作正常,那么 rowspan="10000" 也应该工作。
编辑:哦,是的,根据几个网站,rowspan="0" 到目前为止仅在 Opera 中可以正常工作。
How about trying like this?
At least on this table it looked like it worked in IE8 and FF 3.6. I'm assuming that if rowspan="10" works fine on a table with 3 rows that has 2 sections (2 rows first, 1 row second) then rowspan="10000" should work as well.
Edit: oh yea, according to a couple of sites, the rowspan="0" works correctly so far only in Opera.
