如何删除此表上的双边框？

Question

我正在研究HTML和CSS,我得到的结果并不完美:

我在这里创造了一个小提琴:http://jsfiddle.net/niklasro/GParb/

但桌子的边框似乎与所需屏幕截图的边框不匹配.如何使布局看起来更像原始模型并删除表格上的双边框？

这是我对表格的CSS和HTML代码:

CSS

table{ width:100%; text:align:center;border:1px solid #00F; font-size:12px;}
th{background:#EEE;width:auto; text-align:center; padding:5px 0;border:1px solid #00F;}
td{width:auto; text-align:center; padding:5px 0;border:1px solid #00F;}
tr:nth-child(even) {background: #EEE;}

HTML

<table>
    <thead>
    <tr>
        <th></th>
        <th></th>
        <th></th>
        <th></th>

Answer 1

添加border-collapse:collapse;到表css选择器.这将消除嵌套边框外观.而且,你Text:align:center;应该真的text-align:center;

小提琴:http://jsfiddle.net/GParb/1/

CSS

table{
    width:100%;
    border-collapse:collapse;
    text-align:center;
    border:1px solid #00F;
    font-size:12px;
    }

与cellspacing="0"下面建议的不同,这个答案会将边框折叠成不是3D效果,就像OP要求的那样.

如何删除该表格上的双边框？

1. 删除表格的双边框外观

只需编辑您的表标签，如下所示：

<table cellspacing="0" border="1"> ...</table>

要为边框添加颜色，请添加：bordercolor="#00F"

演示

但是表格的 cellpadding、cellspacing、border 等都是已弃用的属性。相反，您可以使用下表中与上述内容等效的CSS 样式：

2. 删除表格的双边框外观并获得问题中所示图像的精确输出

最佳解决方案：用于border-collapse:collapse;元素<table>。
