我想做一个这样的表
是否可以在表格中添加倾斜的对角线边框？
解决方法
基于
CSS3 linear-gradients解决方案,但角度不是硬编码的：
table:nth-of-type(1) td {
background-image: linear-gradient(
to top right,white 48%,black,white 52%
);
}
table:nth-of-type(2) td {
background-image: linear-gradient(
to top right,papayawhip calc(50% - 1px),papayawhip calc(50% + 1px)
);
}
/* for testing */
table {
border-collapse: collapse;
margin-top: 1em;
margin-bottom: 1em;
}
td:nth-child(odd) {
width: 10em;
}
td:nth-child(even) {
width: 20em;
}
<table border="1">
<tbody>
<tr>
<td>Narrow</td>
<td>Wide</td>
</tr>
<tr>
<td>Narrow</td>
<td>Wide</td>
</tr>
</tbody>
</table>
<table border="1">
<tbody>
<tr>
<td>Narrow</td>
<td>Wide</td>
</tr>
<tr>
<td>Narrow</td>
<td>Wide</td>
</tr>
</tbody>
</table>
