css - 电子邮件的动态高度 100% td

Question

在表格电子邮件的上下文中。我正在寻找我的单元格列的动态高度宽度图像，未知高度由我在 rowspan 中的内容动态定义:

* {padding: 0;}
table { border-collapse: collapse; }
img {width: 100%; height: 100%; display: block; }

<table width="300">
  <tr>
    <td colspan="3" height="20" width="100%"><img src="data:image/gif;base64,R0lGODlhAQABAIAAAAUEBAAAACwAAAAAAQABAAACAkQBADs=" /></td>
  </tr>
  <tr>
    <td width="20" height="20">
      <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAUEBAAAACwAAAAAAQABAAACAkQBADs=" />
    </td>
    <td rowspan="2" width="260" align="top">
      my content dynamic<br />
      my content dynamic<br />
      my content dynamic<br />
      my content dynamic<br />
      my content dynamic<br />
      my content dynamic
    </td>
    <td width="20" height="20">
      <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAUEBAAAACwAAAAAAQABAAACAkQBADs=" />
      </td>
  </tr>
  <tr>
    <td width="20" height="100%">
      <img src="data:image/gif;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAADUlEQVR42mP8zxDxHwAFtQJYX0yrrAAAAABJRU5ErkJggg==" />
      </td>
    <td width="20" height="100%">
      <img src="data:image/gif;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAADUlEQVR42mP8zxDxHwAFtQJYX0yrrAAAAABJRU5ErkJggg==" />
    </td>
  </tr>
</table>

在我的示例中，这是我想要的高度为 100% 的 2 个粉红色列。它用于电子邮件，所以我不能使用绝对位置或 JS 技巧(根据 caniuse for email 以覆盖最多客户)

只需给粉色单元格一个 bgColor 属性即可。

* {padding: 0;}
table { border-collapse: collapse; }
img {width: 100%; height: 100%; display: block; }

<table width="300">
  <tr>
    <td colspan="3" height="20" width="100%"><img src="data:image/gif;base64,R0lGODlhAQABAIAAAAUEBAAAACwAAAAAAQABAAACAkQBADs=" /></td>
  </tr>
  
  <tr>
    <td width="20" height="20">
      <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAUEBAAAACwAAAAAAQABAAACAkQBADs=" />
    </td>
    <td rowspan="2" width="260" align="top">
      my content dynamic<br /> my content dynamic<br /> my content dynamic<br /> my content dynamic<br /> my content dynamic<br /> my content dynamic
    </td>
    <td width="20" height="20">
      <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAUEBAAAACwAAAAAAQABAAACAkQBADs=" />
    </td>
  </tr>
  <tr>
    <td width="20" bgColor="#ff0458">
      <img src="data:image/gif;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAADUlEQVR42mP8zxDxHwAFtQJYX0yrrAAAAABJRU5ErkJggg==" />
    </td>
    <td width="20" bgColor="#ff0458">

  </tr>
