 先前测试就用控制台生成html标签   将生成的html标签在页面展示即可 效果图如下 

 css
     {

        / old-style reset here :) /

        border: 0px;

        padding: 0px;

    }

    body {

        font-family: Helvetica;

        background: white;

        text-align: center;

        / background: url(../img/body.png) repeat-x; */}

    body h1 {

        padding-top: 20px;

        font-size: 36px;

        color: #335;

    }

    p{font-size:26px;}

    table {

        border-collapse: separate;

        border: 1px solid #9DABCE;

        border-width: 1px 1px 1px 1px;

        margin: 10px auto;

        font-size: 30px;

    }

td, th {  
    width: 81px;  
    height: 81px;  
    text-align: center;  
    vertical-align: middle;  
    /*background: url(../img/cells.png);*/  
    color: #444;  
    position: relative;  
}  
th {  
    height: 30px;  
    font-weight: bold;  
    font-size: 14px;  
}  

td.sign_in {  
    background-position: 81px 0px;  
    color: red;  
}  

td.sign_no{  
    background: url(../img/cells.png);
