position: 'sticky'
landed in Chrome 56,但在某些情况下会使边框不可见。
考虑以下示例:
table {
border-collapse: collapse;
}
thead {
position: sticky;
top: 0;
}
th {
background-color: #fff;
border-right: 5px solid red;
}
<table>
<thead>
<tr>
<th>First</th>
<th>Second</th>
<th>Third</th>
</tr>
</thead>
</table>
在Chrome 56.0.2924.76中,只有最后<th>
个边框可见,而且仅当<th>
指定了background-color
时才会显示。
这是Chrome中的错误吗?

我遇到了同样的问题。我的解决方法是使用:after
伪元素来模拟底部边框。
th:after{
content:'';
position:absolute;
left: 0;
bottom: 0;
width:100%;
border-bottom: 1px solid rgba(0,0,0,0.12);
}

如果表格包含列的边框,我们会添加粘贴位置, 当我们滚动表格显示重叠效果以删除此效果和 保留边框我们需要删除边框并添加轮廓而不是边框
table tr th{
outline: 1px solid #e9ecef;
border:none;
outline-offset: -1px;
}

似乎强迫回流会部分帮助:
table {
border-collapse: collapse;
}
thead {
position: sticky;
top: 0;
}
th {
border-right: 5px solid red;
transform:scale(0.999);
}
<table>
<thead>
<tr>
<th>First</th>
<th>Second</th>
<th>Third</th>
</tr>
</thead>
</table>
background-clip
似乎也是有效且无害的:
table {
margin-top: 1em;
border-collapse: collapse;
margin-bottom: 200vh
}
thead {
position: sticky;
top: 0;
}
th {
border-right: 5px solid red;
background:white;
background-clip: padding-box;
}
<table>
<thead>
<tr>
<th>First</th>
<th>Second</th>
<th>Third</th>
</tr>
</thead>
</table>

下一个示例目前在Chrome(65)和Firefox(59)下运行良好。
SCSS代码更好地说明了值之间的关系。您可以通过更改变量来设置所需的值。
SCSS:
table {
&.sticky-table-head {
// Variables
$border-width: 2px;
$head-background-color: #ded;
$head-border-color: #8a8;
$background-color: #f8fff8;
$border-color: #cdc;
$color: #686;
// Declarations
margin-bottom: 1em;
border-collapse: collapse;
background-color: $background-color;
color: $color;
&:last-child {
margin-bottom: 100vh;
}
th,
td {
border: $border-width solid $border-color;
}
thead {
th {
position: sticky;
top: ($border-width / 2);
background-color: $head-background-color;
outline: $border-width solid $head-border-color;
outline-offset: (- $border-width / 2);
}
}
}
}
HTML和编译的CSS:
table.sticky-table-head {
margin-bottom: 1em;
border-collapse: collapse;
background-color: #f8fff8;
color: #686;
}
table.sticky-table-head:last-child {
margin-bottom: 100vh;
}
table.sticky-table-head th,
table.sticky-table-head td {
border: 2px solid #cdc;
}
table.sticky-table-head thead th {
position: -webkit-sticky;
position: sticky;
top: 1px;
background-color: #ded;
outline: 2px solid #8a8;
outline-offset: -1px;
}

使用::after
伪选择器模拟右边框
示例:
th::after {
content: '';
position: absolute;
top: 0;
right: 0;
height: 100%;
border-right: 1px solid #e7e7e7;
}

content: '';
display: block;

}
我用伪元素而不是边框修复了同样的问题。但不知道为什么会发生这种情况。

我在页面中仅使用水平边框,因此可能需要针对您的特定情况进行调整。通过为表格单元格使用半透明的背景色,我发现它是背景的底端与水平边框重叠。我想垂直边框的右端也一样。为了避免边框重叠,我设置了一个线性渐变,该渐变会填充所有内容,但会保留最后一个像素。不幸的是,这仅适用于Firefox和Chrome,不适用于Edge。
td:first-child
{
position: sticky;
left: 0px;
z-index: 2;
background: linear-gradient(to bottom, white, white calc(100% - 1px), transparent calc(100% - 1px), transparent);
}
Edge确实绘制了线性渐变,但从顶部的白色到底部的透明,忽略了停止在100%-1px处的硬变化。

另一种选择是将内容包装在一个元素中并在其上放置边框:
<th><div class="th-inner">your content</div><th>
.th-inner {
padding: 10px;
border-bottom: 1px solid #ccc;
}
但是,我发现将边框放在th
上而不需要在桌子上放置border-collapse: collapse
,所以我去了。

将起作用。但这确实是一个错误,应该由浏览器修复。
