HTML 表头/行对齐
Posted
技术标签:
【中文标题】HTML 表头/行对齐【英文标题】:HTML table header/row alignment 【发布时间】:2022-01-10 11:00:03 【问题描述】:关于这个主题已经写了很多变体(太多了?),以至于人们想知道为什么在 css 或 html 中都没有给出一个优雅的解决方案:标题边界和数据之间的耦合列 (thead/tbody)。
我还是没弄好,抱歉。 我做错了什么?想念什么? 还是这种方式根本不可能,我需要javascript吗?
明确地说,我希望标题与使用 CSS 的表数据列对齐。所以在一个简单的视图中,第 8 个标题字段需要比滚动条的宽度宽一点。单元格的宽度现在由样式宽度说明符确定并自动计算。显然我无法在 tbody 和 thead 之间建立耦合。
请注意,表格的水平调整大小已正确处理。 另请注意,注释掉的是 width: calc(100% - 17px); 这反映了我的部分实验。该示例有点复杂,以保留其可能在问题中起作用的原始格式。
见jsfiddle。

【问题讨论】:
【参考方案1】:我对 CSS 做了一些更改,所以现在 <th>
和 <td>
垂直对齐。 <thead>
已向内移动了滚动条的大小。问题是表的大小是固定的,还是会包含很多数据,因为如果我减少行数,我会用javascript解决。

【讨论】:
您好,感谢您的回复。确实有效。但是,如果我这样做,例如 .CUtable th,它会失败。虽然我当时所做的只是说 .CUtable 类中的所有内容,但不是这样。那么区别在哪里呢? 另外我看不懂` th, td width: 33.33%;填充:5px;断词:打破一切; ` 我也不明白为什么该广告有 display: table; 如果我很好地理解了这个解决方案,你说它只能通过近似来完成(一些填充、一些百分比、一些显示更改等......)。所以它正在解决一个拼图iso算法。这将指向 javascript 的真正解决方案(真实表格将显示 30/31 行,其中显示 10 行(因此溢出滚动条)。 是的,如果滚动条因为数据减少到例如而被消除少于 10 行,<tbody>
将采用<table>
的最大大小。为此,我会使用 javascript 来监控 table 的溢出并将当前的 CSS 调整为。
是的,我也遇到过这种情况,所以我添加了一些 CSS 设置 <thead style="position: sticky; top:0; z-index: 1; background: #d0d0d0; ">
所以标题不会消失在视线范围内....欢迎您!以上是关于HTML 表头/行对齐的主要内容,如果未能解决你的问题,请参考以下文章
