我可以使用CSS对表格列着色而不对单个单元格进行着色

时间:2014-12-01 18:07:25

标签: html css

有没有办法将列的颜色跨越一直向下。请参阅下面的示例:



<table border="1">
  <tr>
    <th>Motor</th>
    <th colspan="3">Engine</th>
    <th>Car</th>
    <th colspan="2">Body</th>
  </tr>
  <tr>
    <td>1</td>
    <td>2</td>
    <td>3</td>
    <td>4</td>
    <td>5</td>
    <td>6</td>
    <td>7</td>
  </tr>
  <tr>
    <td>7</td>
    <td>1</td>
    <td>2</td>
    <td>3</td>
    <td>4</td>
    <td>5</td>
    <td>6</td>
  </tr>
</table>
&#13;
&#13;
&#13;

我正在寻找一种更好的方式(更少的代码,非个人着色)来着色,例如,&#34;引擎&#34;和&#34;身体&#34;跨度,包括#DDD

中的所有单元格

&#13;
&#13;
<style>
  .color {
    background-color: #DDD
  }
</style>
<table border="1">
  <tr>
    <th>Motor</th>
    <th colspan="3" class="color">Engine</th>
    <th>Car</th>
    <th colspan="2" class="color">Body</th>
  </tr>
  <tr>
    <td>1</td>
    <td class="color">2</td>
    <td class="color">3</td>
    <td class="color">4</td>
    <td>5</td>
    <td class="color">6</td>
    <td class="color">7</td>
  </tr>
  <tr>
    <td>7</td>
    <td class="color">1</td>
    <td class="color">2</td>
    <td class="color">3</td>
    <td>4</td>
    <td class="color">5</td>
    <td class="color">6</td>
  </tr>
</table>
&#13;

是的,你可以......使用<col>元素:

&#13;
&#13;
.grey {
  background-color: rgba(128,128,128,.25);
}
.red {
  background-color: rgba(255,0,0,.25);
}
.blue {
  background-color: rgba(0,0,255,.25);
}
&#13;
<table>
  <colgroup>
    <col class="grey" />
    <col class="red" span="3" />
    <col class="blue" />
  </colgroup>
  <thead>
    <tr>
      <th>#</th>
      <th colspan="3">color 1</th>
      <th>color 2</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <th>1</th>
      <td>red</td>
      <td>red</td>
      <td>red</td>
      <td>blue</td>
    </tr>
    <tr>
      <th>2</th>
      <td>red</td>
      <td>red</td>
      <td>red</td>      
      <td>blue</td>
    </tr>
  </tbody>
</table>
&#13;
&#13;
&#13;

注意:您可以使用span属性将col定义应用于多个列。

您可以使用nth-child选择器:

tr td:nth-child(2),
tr td:nth-child(3) {
  background: #ccc;
}
<table>
  <tr>
    <th colspan="2">headline 1</th>
    <th>headline 2</th>
  </tr>
  <tr>
    <td>column 1</td>
    <td>column 2</td>
    <td>column 3</td>
  </tr>
  <tr>
    <td>column 1</td>
    <td>column 2</td>
    <td>column 3</td>
  </tr>
  <tr>
    <td>column 1</td>
    <td>column 2</td>
    <td>column 3</td>
  </tr>
</table>

通常最简单的方法是设置单元格(如果需要,可以按列设置),但可以以不同方式设置列的样式。一种简单的方法是将列包装在colgroup元素中并在其上设置样式。例如:

&#13;
&#13;
<style>
.x {
    background-color: #DDD
}
</style>
<table border="1">
<col>
<colgroup class=x>
  <col>
  <col>
  <col>
</colgroup>
<col>
<colgroup class=x>
  <col>
  <col>
</colgroup>
  <tr>
    <th>Motor</th>
    <th colspan="3" class="color">Engine</th>
    <th>Car</th>
    <th colspan="2" class="color">Body</th>
  </tr>
  <tr>
    <td>1</td>
    <td class="color">2</td>
    <td class="color">3</td>
    <td class="color">4</td>
    <td>5</td>
    <td class="color">6</td>
    <td class="color">7</td>
  </tr>
  <tr>
    <td>7</td>
    <td class="color">1</td>
    <td class="color">2</td>
    <td class="color">3</td>
    <td>4</td>
    <td class="color">5</td>
    <td class="color">6</td>
  </tr>
</table>
&#13;

以下工具是第n个子选择器,应该可以工作......

<style type="text/css">
    th:nth-child(2),
    th:nth-child(4)
    {
        background-color: rgba(255, 0, 0, 1.0);
    }

    td:nth-child(2), 
    td:nth-child(3),
    td:nth-child(4),
    td:nth-child(6),
    td:nth-child(7)
    {
        background-color: rgba(255, 0, 0, 0.5);
    }
</style>

  .table td:nth-of-type(5) {

我会使用nth-child css伪类:

tr td:nth-child(2), tr th:nth-child(2), tr td:nth-child(3), tr td:nth-child(4), tr th:nth-child(4), tr td:nth-child(6), tr td:nth-child(7){
    background-color: #DDD;
}

tr td:nth-child(2),
tr th:nth-child(2),
tr td:nth-child(3),
tr td:nth-child(4),
tr th:nth-child(4),
tr td:nth-child(6),
tr td:nth-child(7) {
  background-color: #DDD;
}
<table border="1">
  <tr>
    <th>Motor</th>
    <th colspan="3">Engine</th>
    <th>Car</th>
    <th colspan="2">Body</th>
  </tr>
  <tr>
    <td>1</td>
    <td>2</td>
    <td>3</td>
    <td>4</td>
    <td>5</td>
    <td>6</td>
    <td>7</td>
  </tr>
  <tr>
    <td>7</td>
    <td>1</td>
    <td>2</td>
    <td>3</td>
    <td>4</td>
    <td>5</td>
    <td>6</td>
  </tr>
</table>

答案 6 :(得分:4)

我使用nth-child表达式的版本:

使用级联规则的CSS概念首先着色单元格,然后取消我想要透明的那些。第一个选择器选择第一个选择器之后的所有单元格,第二个选择器选择第五个单元格为透明。

<style type="text/css">
  /* colored */
  td:nth-child(n+2) { background-color: #ddd }
  /* uncolored */
  td:nth-child(5) { background-color: transparent }
</style>

<table border="1">
  <tr>
    <th>Motor</th>
    <th colspan="3">Engine</th>
    <th>Car</th>
    <th colspan="2">Body</th>
  </tr>
  <tr>
    <td>1</td>
    <td>2</td>
    <td>3</td>
    <td>4</td>
    <td>5</td>
    <td>6</td>
    <td>7</td>
  </tr>
  <tr>
    <td>7</td>
    <td>1</td>
    <td>2</td>
    <td>3</td>
    <td>4</td>
    <td>5</td>
    <td>6</td>
  </tr>
</table>

答案 7 :(得分:0)

这是一个很老的问题,有很多很棒的答案。只是想添加尚未提及的-nnth-last-child选择器。将CSS应用于多个列时它们很有用,但在样式化之前可能不知道列数,或者有多个宽度不同的表。

/* Select the first two */
table tr td:nth-child(-n + 2) {
  background-color: lightblue;
}

/* Select all but the first two */
table tr td:not(:nth-child(-n + 2)) {
    background-color:lightgreen;
}

/* Select last two only */
table tr td:nth-last-child(-n + 2) {
  background-color:mistyrose;
}

/* Select all but the last two */
table tr td:not(:nth-last-child(-n + 2)) {
    background-color:yellow;
}
