关于这个问题，我已经浏览了许多类似标题的问题，并尝试了许多公认的答案，但仍然得到了不需要的行空间。像许多问题一样，我正在制作一个电子邮件模板，因此我必须使用嵌套表不仅得到我想要的结构，而且要使它在电子邮件中正确呈现。
我尝试过的解决方案没有奏效：
单元格间距=0
天花板=0
边界折叠：折叠
边框间距：0
边距：0 0 0
style=“display:block”用于我的图像
这些似乎都没有什么区别，我无法摆脱行空间。这发生在Chrome/IE/Firefox中。

最佳答案
您应该防止h1，h2元素页边距折叠。
h1, h2 {
margin: 0;
}
a:hover {
text-decoration: none !important;
}
.header h1 {
color: #055d90;
font: normal 25px Georgia, Times, serif;
margin: 0;
font-weight: bold;
padding: 0 0 0px 0;
line-height: 39px;
margin-top: 0;
}
.header p {
color: #cf373e;
font: normal 17px Georgia, Times, serif;
margin: 0;
padding: 0;
line-height: 12px;
font-style: italic;
}
.custinfo h1 {
color: #FFFFFF;
font: normal 25px Tahoma, Times, serif;
background-color: #FF8000;
padding: 10px 0 10px 0;
}
.custinfo h2 {
color: #FFFFFF;
font: normal 15px Tahoma, Times, serif;
background-color: #707070;
padding: 0 0 0 0;
}
.table {
border-collapse: collapse;
}
.table td {
margin: 0;
padding: 0;
display: block;
}
h1,
h2 {
margin: 0;
}<table align="left" width="100%" class="table">
