html - 当水平和垂直滚动条可用时修复表格标题

Question

我想固定 html 表格标题。我的表中有很多列，因此需要垂直滚动条来滚动和查看列数据。我想修复表头，以便当用户向下滚动查看行时，表头是固定的。 请找演示http://jsfiddle.net/ZcLSE/1425/ . 当用户向下滚动时，表头应该是固定的并且对用户可见。请指教。

CSS 代码:

.modal-body {
overflow-y: auto;
}
tbody {
}
thead, tbody tr {
}
thead {
    width: calc( 100% - 1em )
}
table {border-collapse:collapse; height:300px;overflow: auto;
    display: block;}
table td {border:solid 1px #fab; width:100px; word-wrap:break-word;}

html代码:

<button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
    Launch demo modal
</button>

<div id="myModal" class="modal fade">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
                <h4 class="modal-title">Modal title</h4>
            </div>
            <div class="modal-body" id="modal-body">
                <table class="table" border="1">

        </div>
        <!-- /.modal-content -->
    </div>
    <!-- /.modal-dialog -->
</div>
<!-- /.modal -->

PS:垂直和水平滚动条都需要，表头要固定。

我试过解决 fiddle，我相信我遇到了和你一样的问题，thead 变得比容器大。

我会推荐这个JQuery Plugin这是专门为您的需要而制作的。
