javascript - 如何卡住 Bootstrap 表的第一个或前 n 列？

Question

我正在尝试制作在水平和垂直滚动时第一列被卡住的表格。 我已经完成了这个 stackoverflow 问题

bootstrap 3 responsive table with fixed first column

它也有答案，但它有一些错误。我想给 table 固定高度。当我给出表格高度修复时，第一列就会溢出，如这个 fiddle 所示:

http://jsfiddle.net/nt7fd965/144/
JS:

var $table = $('.table');
var $fixedColumn = $table.clone().insertBefore($table).addClass('fixed-column');

$fixedColumn.find('th:not(:first-child),td:not(:first-child)').remove();

$fixedColumn.find('tr').each(function (i, elem) {
    $(this).height($table.find('tr:eq(' + i + ')').height());
});

CSS:

.table-responsive>.fixed-column {
    position: absolute;
    display: inline-block;
    width: auto;
    border-right: 1px solid #ddd;
}
@media(min-width:768px) {
    .table-responsive>.fixed-column {
        display: none;
    }
}

HTML:

<div class="table-responsive" style="height:300px">
<table class="table table-striped table-bordered table-hover table-condensed">
    <thead>
        <tr>
            <th>#</th>

            <th>Table heading</th>
            <th>Table heading</th>
            <th>Table heading</th>
            <th>Table heading</th>
        </tr>
    </thead>
    <tbody>

这里是解决方案 demo

table {
width: 100%;
}

thead, tbody, tr, td, th { display: block; }

tr:after {
content: ' ';
display: block;
visibility: hidden;
clear: both;
}

thead th {
height: 30px;

/*text-align: left;*/
}

tbody {
height: 120px;
overflow-y: auto;
}

thead {
/* fallback */
}


tbody td, thead th {
width: 19.2%;
float: left;
}

<table class="table table-striped">
