HTML – 如何像桌子一样设置无序列表的样式？

ul {
    width: 450px;           /* change it to whatever you like */
    position: relative;

    /* these should be probably already set up by `reset.css` */ 
    list-style-type: none;
    margin: 0;
    padding: 0;
}

ul:before,ul:after {
    text-align: center;
    display: block;
    border: 1px solid black;
    border-bottom: 0;
    width: 48%;
}

ul:before {
    content: 'col1';
    border-right: 0;    
}

ul:after {
    content: 'col2';
    position: absolute;
    top: 0;
    left: 48%;
    margin-left: 1px;    
}

li {
    text-align: right;
    width: 48%;
    float: left;
    border: 1px solid black;
    margin-bottom: -1px;
}

li:nth-child(even) {
    margin-left: -1px;
}

它可以工作(JSFiddle;在Chrome,Firefox和Opera中测试; nth-child(偶数)选择器在IE8中明显失败,所以你必须用类或其他方式模拟它;但是否则它仍然很稳定),但我承认我感到内疚对这个. )

附：如果要为“单元格”内容添加填充,请不要忘记更改其宽度,如here：

li {
    width: 47%;
    padding-right: 1%;
}
