删除 table 行之间的间距

Question

我查看了许多关于此问题的类似标题的问题，并尝试了许多已接受的答案，但仍然得到不需要的行空间。像许多问题一样，我正在制作一个电子邮件模板，所以我必须使用嵌套表格来获得我想要的结构，而且要使其在电子邮件中正确呈现。

我尝试过但没有奏效的解决方案：

单元格间距 = 0
单元格填充 = 0
border-collapse：崩溃
border-spacing: 0
边距：0 0 0 0
风格="display: block" 我的形象

None 这些似乎甚至有所作为，我无法摆脱行空间。这发生在 Chrome/IE/Firefox。

Answer 1

您应该防止 h1、h2 元素发生边距折叠。

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">
  <tr>
    <!--header-->
    <table class="table" cellpadding="0" cellspacing="0" width="100%" style="border-collapse: collapse;  border-spacing: 0; margin-top: 0;">
      <tr>
        <td valign="top">
          <img src="images/logo.gif" style="display: block; border: 0" alt="" width="200" height="100">
        </td>
      </tr>
      <tr>
        <td valign="top" align="middle" class="header" width="100%">
          <h1>Order</h1>

        </td>
      </tr>
    </table>
    <table class="table" cellpadding="0" cellspacing="0" width="100%" style="border-collapse: collapse;  border-spacing: 0;">
      <tr class="custinfo">
        <td width="50%">
          <h1>[DISTRIBUTOR NAME]</h1> 
        </td>
        <td align="middle">
          <h1>[ORDER DATE]</h1>

        </td>
      </tr>
    </table>
    <table class="table" cellpadding="0" cellspacing="0" width="100%" style="border-collapse: collapse;  border-spacing: 0;">
      <tr class="custinfo">
        <td>
          <h2>PO# [PO NUMBER]</h2> 
        </td>
        <td>
          <h2>Customer [COMPANY NAME]</h2>

        </td>
        <td>
          <h2>Total Order [TOTAL ORDER]</h2>

        </td>
      </tr>
      <tr class="custinfo" style="margin:0">
        <td>
          <h2>PO# [PO NUMBER]</h2> 
        </td>
        <td>
          <h2>Customer [COMPANY NAME]</h2>

        </td>
        <td>
          <h2>Total Order [TOTAL ORDER]</h2>

        </td>
      </tr>
    </table>

参考：Margin collapsing

Answer 2

将 margin: 0 添加到您的 h2。如果您未定义边距 0，则边距默认为用户代理样式表。

Css代码

.custinfo h2 {
  color: #FFFFFF;
  font: normal 15px Tahoma, Times, serif;
  background-color: #707070;
  padding: 0 0 0 0;
  margin: 0;
}
