Question

远左边框在整个表格中都不显示任何内容。我如何在下面的CSS代码中修复它？边框现在显示所有其他细胞都很好的颜色。

以下是我现有的CSS代码。提前致谢。

Answer 1

如果我理解得对，你想要左td的相同边框。你可以用这个：

td:first-child {
    border-left: 1px solid #C1DAD7;
}

#mytable {
  padding: 0;
  margin: 0;
  border-spacing: 0px;
  border-collapse: separate;
}
caption {
  padding: 0 0 5px 0;
  width: 700px;
  font: italic 11px"Trebuchet MS", Verdana, Arial, Helvetica, sans-serif;
  text-align: right;
}
th {
  font: bold 11px"Trebuchet MS", Verdana, Arial, Helvetica, sans-serif;
  color: #4f6b72;
  border-right: 1px solid #C1DAD7;
  border-bottom: 1px solid #C1DAD7;
  border-top: 1px solid #C1DAD7;
  letter-spacing: 2px;
  text-transform: uppercase;
  text-align: center;
  padding: 6px 6px 6px 12px;
  background: #CAE8EA url(/images/bg_header.jpg) no-repeat;
}
th.nobg {
  border-top: 0;
  border-left: 0;
  border-right: 1px solid #C1DAD7;
  background: none;
}
td {
  border-right: 1px solid #C1DAD7;
  border-bottom: 1px solid #C1DAD7;
  background: #fff;
  padding: 6px 6px 6px 12px;
  color: #4f6b72;
}
td.alt {
  background: #F5FAFA;
  color: #797268;
}
th.spec {
  border-left: 1px solid #C1DAD7;
  border-top: 0;
  background: #fff url(/images/bullet1.gif) no-repeat;
  font: bold 10px"Trebuchet MS", Verdana, Arial, Helvetica, sans-serif;
}
th.specalt {
  border-left: 1px solid #C1DAD7;
  border-top: 0;
  background: #f5fafa url(/images/bullet2.gif) no-repeat;
  font: bold 10px"Trebuchet MS", Verdana, Arial, Helvetica, sans-serif;

    <td>TEST
      <td>TEST</td>

Answer 2

好吧，您可以在border-left: 1px solid #C1DAD7;定义中添加td，也可以在border-collapse: separate;中将border-collapse: collapse;更改为#mytable。

也可以在border-left: 1px solid #C1DAD7;的整个表格中添加左#mytable。

Answer 3

常见的解决方案是使用:first-child或相邻的运算符：+但IE6中不支持这些运算符。如果需要，您可能需要为这些样式单独处理该浏览器。（可能使用条件评论？）

无论如何，我试图拿出相关的CSS并假设有关标记的一些事情来提出这个：

#mytable {
    padding: 0;
    margin: 0;
    border-spacing: 0px;
    border-collapse: separate;
    border: 1px solid #C1DAD7;
}
td + td, th + th {
    border-left: 1px solid #C1DAD7;
}
tr + tr {
    border-top: 1px solid #C1DAD7;
}

td {
    background: #fff;
    padding: 6px 6px 6px 12px;
    color: #4f6b72;
}

th {
    font: bold 11px "Trebuchet MS", Verdana, Arial, Helvetica, sans-serif;
    color: #4f6b72;
    letter-spacing: 2px;
    text-transform: uppercase;
    text-align: center;
    padding: 6px 6px 6px 12px;
    background: #CAE8EA url(/images/bg_header.jpg) no-repeat;
}

<table id="mytable">
    <tr>
        <th>TEST1</th>
        <th>TEST2</th>
        <th>TEST3</th>
        <th>TEST4</th>
    </tr>
    <tr>
        <td>TEST1</td>
        <td>TEST2</td>
        <td>TEST3</td>
        <td>TEST4</td>
    </tr>
</table>
