我有一个场景，需要将表格底部行的每个th标签移动到滚动div的底部。以下是plnkr链接。我可以使用硬编码来移动它。
$('.sticky-table').find("table tfoot tr.sticky-row th").css('top', 260);
但我想计算260并且做到它。需要帮助。

您需要计算整个容器的底部位置，然后从中减去页脚、页眉和水平滚动条的高度。这将得到页脚行 th 元素的顶部位置。
$('.sticky-table.sticky-headers').offset().top //top of the container
+ $('.sticky-table.sticky-headers').outerHeight() //height of the container (adding it with top gives you the bottom position of the container)
- $('.sticky-table').find("table tfoot tr.sticky-row th").outerHeight(true) //height of the footer headers
- 11 //Fixed height of the scrollbar
更新了plunker。

谢谢。我通过这段代码实现了创建固定表头、列和页脚的表格的目标。 - Ghazanfar Khan

这可以通过几行简单的CSS代码实现。这能够消除在jQuery中基于高度和位置进行的复杂计算的需要，并且如果需要，具有响应式的附加优势。目标是将
tfoot元素绝对定位在.sticky-table元素的底部。为此，我们可以给.sticky-table设置position:relative;，并为tfoot设置position:absolute; bottom:0;。.sticky-table {
/* ...existing styles */
position: relative;
}
.sticky-table tfoot {
position: absolute;
bottom: 0;
}
像这样：
/* Styles go here */
.sticky-table {
position: relative;
max-width: 100%;
max-height: 500px;
height: 500px;
overflow: auto;
border-top: 1px solid #ddd;
border-bottom: 1px solid #ddd;
padding: 0 !important;
}
.sticky-table table {
margin-bottom: 0;
width: 100%;
max-width: 100%;
border-spacing: 0;
}
.sticky-table table tr.sticky-row th,
.sticky-table table tr.sticky-row td {
background-color: #fff;
border-top: 0;
position: relative;
outline: 1px solid #ddd;
z-index: 5;
}
.sticky-table table td.sticky-cell,
.sticky-table table th.sticky-cell {
background-color: #fff;
outline: 1px solid #ddd;
position: relative;
z-index: 10;
}
.sticky-table table tr.sticky-row td.sticky-cell,
.sticky-table table tr.sticky-row th.sticky-cell {
z-index: 15;
}
.sticky-table tfoot {
position: absolute;
bottom: 0;
}
.sticky-table::-webkit-scrollbar {
width: 0.7em;
height: 0.7em;
}
.sticky-table::-webkit-scrollbar-track {
-webkit-box-shadow: inset 0 0 6px rgba(0, 0, 0, 0.3);
}
.sticky-table::-webkit-scrollbar-thumb {
background-color: #b37e7e;
outline: 1px solid slategrey;
border-radius: 5px;

.css('bottom', 0);来定义距离底部的距离吗？这样比定义距离顶部更方便。 - Adriano
