table scrollbar & header fixed

有很多页面由于数据量过大，会产生横纵滚动条。为了便于使用者观看，我们要把表头固定一下。根据这个需求写了个demo来实现这个功能。

主要解决了几点问题：
1.table实现横纵滚动条
2.table表头固定
3.table列宽自适应
4.table内容不换行

css：

            .table-scroll {
                width: calc(100% - 5px);
                overflow-x: scroll;
                white-space: nowrap;
            }

            .table-scroll table {
                table-layout: fixed;
                width: calc(100% - 10px);
                background-color:darkseagreen ;
            }

            .table-scroll thead {
                display: table-row;
                background-color: bisque;
            }

            .table-scroll tbody {
                overflow-y: scroll;
                overflow-x: hidden;
                display: block;
                height: calc(100vh - 300px);
            }

            .table-scroll th,td {
                width: 160px;
                overflow: hidden;
                text-overflow: ellipsis;
                min-width: 160px;
                border: 1px solid #808080;
            }

            h4, h5 {

网上也有很多的例子，但是实现的效果不是想要的，自己工作需要做了一下，画面不好看，重点看效果，如有问题请指正！
