直接上主题，首先是运行效果：

具体的代码如下：

文件名：test.css

table.t1 {
        margin-top:10px;
        margin-left:20px;
        margin-right:20px;
        margin-bottom:5px;
        #background-color: #FFF;
        #background:#EEF4F9;
        #border: none;
        border: 1;
        #color:#003755;
        border-collapse:collapse;
        font: 14px  "宋体";
}

table.t1 th{
        background:#7CB8E2;
        color:#fff;
        padding:6px 4px;
        text-align:center;
}

table.t1 td{
        background:#C7DDEE none repeat-x scroll center left;
        color:#000;
        padding:4px 2px;
}

table.t1 a{
        text-decoration:none;
        height:1em;
}

table.t1 a:link, table.t1  a:visited{
        color:#3366CC;
}
table.t1  a:hover{                                      /* 鼠标经过时 */
        color:#B50000;
        text-decoration:underline;
}
