table表头固定，内容可滚动问题

1.首先新建html页面body中写入：

<div class="title_div" id="tdiv">
    <table class="title_tb" id="tb1">
        <tr>
            <td width="80">文件类型</td>
            <td width="80">文件名</td>
            <td width="80">大小</td>
            <td width="80">全景</td>
            <td width="80">状态</td>
            <td width="150">操作</td>
        </tr>
    </table>
</div>
<div class="data_div" id="ddiv">
    <table class="title_tb" id="tb2">
        <tr>
            <td width="80">0</td>
            <td width="80">gaaaaaaaaadddddsssssssssssssssssssssssssssseeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee</td>
            <td width="80">图片亲子乐园亲子乐园亲子乐园亲子乐园亲子乐园</td>
            <td width="80">300kb亲子乐园亲子乐园亲子乐园亲子乐园亲子乐园亲子乐园亲子乐园亲子乐园亲子乐园亲子乐园亲子乐园</td>
            <td width="80">上传成功亲子乐园亲子乐园亲子乐园亲子乐园亲子乐园亲子乐园亲子乐园</td>
            <td class="last_td" width="150">
                <div class="delate"><a href="">删 除</a></div>
                <div class="upload"><a href="">重新上传</a></div>
            </td>

        </tr>
        <tr>
            <td>1</td>
            <td>图片</td>
            <td>300kb</td>
            <td>是</td>
            <td>上传成功</td>
            <td class="last_td">
                <div class="delate"><a href="">删 除</a></div>
                <div class="upload"><a href="">重新上传</a></div>
            </td>
        </tr>
        <tr>
            <td>亲子乐园</td>
            <td>图片</td>
            <td>300kb</td>
            <td>是</td>
            <td>上传成功</td>
            <td class="last_td">
                <div class="delate"><a href="">删 除</a></div>
                <div class="upload"><a href="">重新上传</a></div>
            </td>
        </tr>
        <tr>
            <td>亲子乐园</td>
            <td>图片</td>
            <td>300kb</td>
            <td>是</td>
            <td>上传成功</td>
            <td class="last_td">
                <div class="delate"><a href="">删 除</a></div>
                <div class="upload"><a href="">重新上传</a></div>
            </td>
        </tr>
        <tr>
            <td>亲子乐园</td>
            <td>图片</td>
            <td>300kb</td>
            <td>是</td>
            <td>上传成功</td>
            <td class="last_td">
                <div class="delate"><a href="">删 除</a></div>
                <div class="upload"><a href="">重新上传</a></div>
            </td>
        </tr>
        <tr>
            <td>亲子乐园</td>
            <td>图片</td>
            <td>300kb</td>
            <td>是</td>
            <td>上传成功</td>
            <td class="last_td">
                <div class="delate"><a href="">删 除</a></div>
                <div class="upload"><a href="">重新上传</a></div>
            </td>
        </tr>
    </table>
</div>

2.对表格进行样式编写：

html, body {
            margin: 0;
            padding: 0;
        }

        .title_tb, .data_div {
            overflow: auto;
            border-collapse: collapse;
            cellspacing: 0;
            cellpadding: 0;
            text-align: center;
            table-layout: fixed;
            width: 904px;
        }

        #tb1 td {
            /*width: 80px;*/
            border-bottom: 1px solid #c2d4f2;
            border-right: 1px solid #c2d4f2;
            font-size: 14px;
            text-align: center;
            height: 38px;
            color: #fff;
            background: #4166a2;
        }

        #tb2 td {
            text-indent: 8px;
            border-bottom: 1px solid #c2d4f2;
            border-right: 1px solid #c2d4f2;
            font-size: 14px;
            text-align: center;
            height: 38px;
            color: #626262;
            white-space: nowrap;
            text-overflow: ellipsis;
            overflow: hidden;

        }

        .title_div, .data_div {
            overflow-x: hidden;
            overflow-y: scroll;
            background: white;
        }

        .data_div {
            height: 100px;
        }

        .last_td {
            position: relative;
        }

        .delate {
            position: absolute;
            right: 115px;
            top: 6.5px;
            width: 70px;
            line-height: 25px;
            background: #ccc;
            border-radius: 5px;
        }

        .delate a {
            display: block;
            color: #666;
        }

        .upload {
            position: absolute;
            right: 15px;
            top: 6.5px;
            width: 90px;
            line-height: 25px;
            background: #009688;
            border-radius: 5px;
        }

        .upload a {
            display: block;
            color: #fff;
        }

3.最重要的一步，js进行操作表头和滚动条：

    var jstb1 = document.getElementById("tb1").rows[0];
    var jstb2 = document.getElementById("tb2").rows[0];
    var divw = 0;
    for (var i = 0; i < 6; i++) {
        if (jstb1.cells[i].clientWidth > jstb2.cells[i].clientWidth) {
            jstb2.cells[i].style.width = parseInt(jstb1.cells[i].clientWidth) - 2 + "px";
            divw += parseInt(jstb1.cells[i].clientWidth) - 2;
        } else {
            jstb1.cells[i].style.width = parseInt(jstb2.cells[i].clientWidth) - 2 + "px";
            divw += parseInt(jstb2.cells[i].clientWidth) - 2;
        }
    }
    divw += 27;
    divw += "px";
    document.getElementById("tdiv").style.width = divw;
    document.getElementById("ddiv").style.width = divw;
    document.getElementById("tdiv1").style.width = divw;
    document.getElementById("ddiv1").style.width = divw;
