html - 如何删除这张 table 内壁上的 'double border'？ CSS

Question

我有以下 HTML 和 CSS:

HTML

<table>
    <tbody>
        <tr>
            <td>Row one, cell one</td>
            <td>Row one, cell two</td>
        </tr>
        <tr>
            <td>Row two, cell one</td>
            <td>Row two, cell two</td>
        </tr>
        <tr>
            <td>Row three, cell one</td>
            <td>Row four, cell two</td>
        </tr>
        <tr>
            <td>Row three, cell one</td>
            <td>Row four, cell two</td>
        </tr>
        <tr>
            <td>Row three, cell one</td>
            <td>Row four, cell two</td>
        </tr>
        <tr>
            <td>Row three, cell one</td>
            <td>Row four, cell two</td>
        </tr>
        <tr>
            <td>Row three, cell one</td>
            <td>Row four, cell two</td>
        </tr>
    </tbody>
</table>

CSS

tbody tr:last-child td:first-child {
    border-radius: 0 0 0 0.6em;
}
tbody tr:last-child td:last-child {
    border-radius: 0 0 0.6em 0;
}
tbody tr:first-child td:first-child {
    border-radius: 0.6em 0 0 0;
}
tbody tr:first-child td:last-child {
    border-radius: 0 0.6em 0 0;
}

如果你检查表格，你会看到它有

border-collapse: seperate;
border-spacing: 0;

无论出于何种原因，这些都是获得 flex 边缘所必需的。不幸的是，这也会导致每个单元格的内壁都有一个边框，当细胞一起塌陷时，似乎内壁都有双倍厚的边框。

有没有办法用纯 CSS 或 HTML 来解决这个问题？

Answer 1

像下面这样更新你的 CSS。

table {
   border-spacing: 0;
 }
th, td {
border-bottom:1px solid #000;
border-left:1px solid #000;
padding: 0.5em 1em;
}

tbody tr:last-child td:first-child {
border-radius: 0 0 0 0.6em;    
}
tbody tr:last-child td:last-child {
border-radius: 0 0 0.6em 0;
}
tbody tr:first-child td:first-child {
border-radius: 0.6em 0 0 0;
border-top:1px solid #000;
}
tbody tr:first-child td:last-child {
border-radius: 0 0.6em 0 0;
border-top:1px solid #000;
}
tbody tr td:last-child{
border-right:1px solid #000;
}
