一种局部固定表头的实现方案（横向可跟随内容一同滚动，纵向锁定表头）

1.为了固定表头我们需要先把表格的head和tbody切分到两个table里： <table class="table-head"></table>和 <table class="table-body"></table>里。

2.将table-body放在一个table-body-box的div里设置y轴方向可以滚动，x轴方向不可滚动，这样表内容就能在自己的区域实现垂直方向的滚动了。
3.将table-head设置为absolute

4.将table-head和table-body-box的div放入一个table-box的div中，设置横向x轴可以滚动，y轴不可滚动。
这样两个表就会在x方向滚动，y轴不滚动，表头就垂直方向固定在垂直方向，横向滚动在table-box出现滚动条的时候，内部的表格头和表格内容因为没有设置为fixed，所以会被滚动。

表头和表内容的横向方向滚动能力（其实是父级overflow-x:scroll样式赋予的）。表内容的垂直方向滚动是通过表内容外套的table-body-box设置overflow-y:scroll来实现的。

5.代码如下：

<style>
.table-box {
    height: 100%;
    width: 100%;
    overflow-y: hidden;
    overflow-x: scroll;
    -webkit-overflow-scrolling: touch;
    position: relative;
}

.table-head {
    background-color: #F9FAFE;
    border-top: 1px solid #e8e8e8;
    border-bottom: 1px solid #e8e8e8;
    color: #777;
    table-layout: fixed;
    position: absolute;
    top:0;
}

.table-head th {
    border-collapse: collapse;
    height: 40px;
}

.table-body-box {
    table-layout: fixed;
    -webkit-overflow-scrolling: touch;
    overflow-x: hidden;
    overflow-y: scroll;
    height: 100%;
    box-sizing: border-box;
    padding-top: 50px;
}

.table-body{
    table-layout: fixed;
    width: 100%;
    background-color: white;
    text-align: center;
}
.table-body tr:nth-child(even) {
    background-color: #F9FAFE;
}
</style>


html如下
        <div style="height:500px">
            <div class="table-box">
                <table class="table-head"  style="width: 900px">
                    <colgroup>
                        <col width="150">

                        <col>

                        <col>
