Html gmail中的电子邮件签名问题

我已经创建了一个电子邮件签名。当我在浏览器中打开签名时，它看起来不错，但是每当我试图在Gmail中使用它时，签名就显得不成比例。看起来gmail忽略了一些CSS。 我的收件箱中就是这样出现的：

代码如下：

<div id="handtekening" style="width:650px;">

<span style="padding-bottom:30px;">Met vriendelijke groeten,</span>

<table style="width:650px; font-family:Open Sans, sans-serif; border-spacing: 0px; margin-top:40px;">
