在表格中居中表格
我整个星期都在为这个我需要尽快发送的电子邮件而苦苦挣扎。我需要将这些产品图像与它们的描述放在一起，但我似乎无法浏览代理机构移交的这个模板。
我曾尝试更改显示属性并添加许多其他属性和方法，例如添加顶部填充（这在构建器中可以直观地工作，但在测试时它仍然卡在桌子的顶部）。这个电子邮件完全是用 HTML 制作的，带有内联 CSS 元素，并且为这些表指定了一个类，但是我在这个 HTML 中找不到它们的“全局”CSS 属性。
如果问题看起来含糊不清，我对所有这些都很陌生，所以很抱歉。我附上了问题的截图。
如您所见，产品图像与表格顶部对齐，无论我尝试什么，它们都无法移动到描述的中心：

使用style="vertical-align: middle;"的，而不是valign="top"对th包含子表与图像：

</tr>请注意：包含子表的单元格th 在您的代码中是 a ，但在语义上不适用 - 它绝对不包含 任何类型的标题，这就是th它的用途。
另外，我不明白为什么您使用的是嵌套表只包含一个行和单元格-您可以也简单地把图像转换成“父”小区（th我说的是，这应该宁可一td）和把它放在那里。
