HTML - Outlook 客户端高度问题
HTML - Outlook clients height issue
请参阅以下代码获取 HTML 电子邮件；
<table class="barcode" style="border-collapse:collapse; border:none !important; background:white; width:auto; margin: auto;">
<tr style="height: 50px;">
<!-- This is duplicated -->
<td style="height: 50px; padding:0 0 0 0; margin:0 0 0 0; background:white; border-width:0 0 0 1.6px; border-left-color: black; border-left-style: solid;">
<table style="border-collapse: collapse"><tr>
<td height="50" width="4.3" style="visibility:hidden; width:4.3px; height:50px; font-size:4px; color:#FFFFFF; color:transparent; padding: 0">█</td>
</tr></table>
</td>
<!-- /This is duplicated -->
</tr>
</table>
注释之间的 <td> 元素重复多次（出于条形码原因）。但是，当您超过 100 (appx) <td> 个元素时，Outlook 客户端似乎会忽略 50px height。屏幕截图如下。

我已经尝试删除粗嵌套 table 并将其替换为 div，但仍然遇到同样的问题。
当我超过 x 个 <td> 元素时，为什么 Outlook 客户端会忽略 50px height？
问题很简单，Outlook喜欢tables有高度和宽度，会忽略样式。每个table加上height="50"，问题就解决了
<table height="50" class="barcode" border="2" style="border-collapse:collapse; border: none!important; background:white; width:auto; margin: auto; height: 50px!important;">
<tr style="height: 50px;">
<td height="50" style="height: 50px; padding:0 0 0 0; margin:0 0 0 0; background:white; border-width:0 0 0 1.6px; border-left-color: black; border-left-style: solid;">
<table height="50" style="border-collapse: collapse">
<tr>
<td height="50" width="4.3" style="visibility:hidden; width:4.3px; height:50px; font-size:4px; color:#FFFFFF; color:transparent; padding: 0">█</td>
</tr>
</table>
</td>
<td style="height: 50px; padding:0 0 0 0; margin:0 0 0 0; background:white; border-width:0 0 0 1.6px; border-left-color: black; border-left-style: solid;">
<table height="50" style="border-collapse: collapse">
<tr>
<td height="50" width="2.3" style="visibility:hidden; width:2.3px; height:50px; font-size:2px; color:#FFFFFF; color:transparent; padding: 0">█</td>
</tr>
</table>
</td>
<td style="height: 50px; padding:0 0 0 0; margin:0 0 0 0; background:white; border-width:0 0 0 1.6px; border-left-color: black; border-left-style: solid;"> </td>
</tr>
</table>
祝你好运。
我删除了所有内部表格和宽度，只保留了外部 td，它现在可以在 Outlook 2016 中使用 版本 1802（内部版本 9029.2167）。
现在您需要的是另一组用白色分隔条码行的 td。
<table class="barcode" style="border-collapse:collapse; border:none !important; background:white; width:auto; margin: auto;">
<tbody>

建议：不要使用边框，使用带像素宽度的 td 并为其指定背景颜色。
让我知道这是否适合你。
请参阅以下代码获取 HTML 电子邮件；

注释之间的 <td> 元素重复多次（出于条形码原因）。但是，当您超过 100 (appx) <td> 个元素时，Outlook 客户端似乎会忽略 50px height。屏幕截图如下。
https://jsfiddle.net/uqtzov9u/1/ - 生成上述内容的代码
我已经尝试删除粗嵌套 table 并将其替换为 div，但仍然遇到同样的问题。
当我超过 x 个 <td> 元素时，为什么 Outlook 客户端会忽略 50px height？
问题很简单，Outlook喜欢tables有高度和宽度，会忽略样式。每个table加上height="50"，问题就解决了
<table height="50" class="barcode" border="2" style="border-collapse:collapse; border: none!important; background:white; width:auto; margin: auto; height: 50px!important;">
<tr style="height: 50px;">

祝你好运。
我删除了所有内部表格和宽度，只保留了外部 td，它现在可以在 Outlook 2016 中使用 版本 1802（内部版本 9029.2167）。
现在您需要的是另一组用白色分隔条码行的 td。
