html或css中的倾斜对角线？ [英] Slanted diagonal line in html or css?

问题描述

我想创建一个这样的表

是否可以在表格中添加倾斜对角线边框？

解决方案

根据 CSS3线性渐变解决方案，除了角度不是硬编码：

  table：nth-​​of-type（1）td {background-image：linear-gradient右侧，白色48％，黑色，白色52％）;}表：n类型（2）td {背景图像：线性梯度（右上，番木瓜计算（50％-1px） calc（50％+ 1px））;} / *用于测试* / table {border-collapse：collapse; margin-top：1em; margin-bottom：1em;} td：nth-​​child（odd）{width：10em;} td：nth-​​child（even）{width：20em;}  

pre class =snippet-code-html lang-html prettyprint-override> < 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>

I want to make a Table like this

is it possible to add a slanted diagonal border in table?

解决方案

Based on CSS3 linear-gradients solution except that the angle is not hard coded:

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),
    black,
    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>
