HTML colspan在CSS

我试图构造一个类似于下面的布局:

+---+---+---+
|   |   |   |
+---+---+---+
|           |
+-----------+

底部填充上一行的空间。

如果这是一个实际的表,我可以使用<td colspan="3">轻松完成,但由于我只是创建一个类似于表的布局,所以不能使用<table>标记。这是可能的使用CSS?


<div style="width: 100%;">
    <div style="float: left; width: 33%;">Row 1 - Cell 1</div>
    <div style="float: left; width: 34%;">Row 1 - Cell 2</div>
    <div style="float: left; width: 33%;">Row 1 - Cell 3</div>
</div>
<div style="clear: left; width: 100%;">
Row 2 - Cell 1
</div>

这不是CSS权限的一部分。colspan描述页面内容的结构,或者为表中的数据赋予一些含义,这是HTML的工作。


您可以尝试使用像http://960.gs/这样的网格系统

你的代码应该是这样的,假设你使用的是“12列”布局:

<div class="container_12">
<div class="grid_4">1</div><div class="grid_4">2</div><div class="grid_4">3</div>
<div class="clear"></div>
<div class="grid_12">123</div>
</div>

colspan没有简单、优雅的CSS模拟。

对这个问题的搜索将返回各种解决方案,其中包括一系列替代方案,包括绝对定位、大小,以及类似的各种浏览器和特定环境的警告。阅读,并根据你的发现做出最明智的决定。


据我所知,css中没有colspan,但在不久的将来会有用于多列布局的column-span,但由于它只是CSS3中的草稿,你可以在这里检查它。不管怎样,你可以使用div和span来解决这个问题。

这就是HTML:

<div class="table">
  <div class="row">
    <span class="cell red first"></span>
    <span class="cell blue fill"></span>
    <span class="cell green last"></span>
  </div>
</div>
<div class="table">
  <div class="row">
    <span class="cell black"></span>
  </div>
</div>

这就是css:

  /* this is to reproduce table-like structure
     for the sake of table-less layout. */
  .table { display:table; table-layout:fixed; width:100px; }
  .row { display:table-row; height:10px; }
  .cell { display:table-cell; }

  /* this is where the colspan tricks works. */
  span { width:100%; }

  /* below is for visual recognition test purposes only. */
  .red { background:red; }
  .blue { background:blue; }
  .green { background:green; }
  .black { background:black; }

  /* this is the benefit of using table display, it is able 
     to set the width of it's child object to fill the rest of 
     the parent width as in table */
  .first { width: 20px; }
  .last { width: 30px; }
  .fill { width: 100%; }

使用这个技巧的唯一原因是为了获得表格布局行为的好处,如果仅仅设置div和span宽度到一定的百分比并不能满足我们的设计要求,我就会使用它。

但如果你不需要从表格布局行为中获益,那么durilai的答案将足够适合你。


你可以这样定位:绝对的;并指定宽度。这不是一个很流畅的方法,但这是可行的。


如果使用div和span,当datagrid-table行体积更大时,它将占用更多的代码大小。下面的代码在所有浏览器中都进行了检查

HTML:

<div id="gridheading">
<h4>Sl.No</h4><h4 class="big">Name</h4><h4>Location</h4><h4>column</h4><h4>column</h4><h4>column</h4><h4>Amount(Rs)</h4><h4>View</h4><h4>Edit</h4><h4>Delete</h4> 
</div>
<div class="data"> 
<h4>01</h4><h4 class="big">test</h4><h4>TVM</h4><h4>A</h4><h4>I</h4><h4>4575</h4><h4>4575</h4></div>
<div class="data"> 
<h4>01</h4><h4 class="big">test</h4><h4>TVM</h4><h4>A</h4><h4>I</h4><h4>4575</h4><h4>4575</h4></div>

CSS:

#gridheading {
    background: #ccc;
    border-bottom: 1px dotted #BBBBBB;
    font-size: 12px;
    line-height: 30px;
    text-transform: capitalize;
}
.data {
    border-bottom: 1px dotted #BBBBBB;
    display: block;
    font-weight: normal;
    line-height: 20px;
    text-align: left;
    word-wrap: break-word;
}
 h4 {
    border-right: thin dotted #000000;
    display: table-cell;
    margin-right: 100px;
    text-align: center;
    width: 100px;
    word-wrap: break-word;
}
.data .big {
    margin-right: 150px;
    width: 200px;
}

Media Query类可用于实现带有重复标记的可传递内容。下面是我使用bootstrap的方法:

  <tr class="total">
    <td colspan="1" class="visible-xs"></td>
    <td colspan="5" class="hidden-xs"></td>
    <td class="focus">Total</td>
    <td class="focus" colspan="2"><%= number_to_currency @cart.total %></td>
  </tr>

colspan 1用于移动,colspan 5用于其他使用CSS的工作。


我创造了这把小提琴:

http://jsfiddle.net/wo40ev18/3/

HTML

<div id="table">
<div class="caption">
    Center Caption
</div>
<div class="group">
      <div class="row">
            <div class="cell">Link 1t</div>
            <div class="cell"></div>
          <div class="cell"></div>
          <div class="cell"></div>
            <div class="cell"></div>
            <div class="cell ">Link 2</div>
      </div>
</div>

CSS

   #table {
    display:table;
}

.group {display: table-row-group; }

.row {
    display:table-row;
    height: 80px;
    line-height: 80px;
}

.cell {
    display:table-cell;
    width:1%;
    text-align: center;
    border:1px solid grey;
    height: 80px
        line-height: 80px;
}

.caption {
    border:1px solid red; caption-side: top; display: table-caption; text-align: center; 
    position: relative;
    top: 80px;
    height: 80px;
      height: 80px;
    line-height: 80px;

}

尝试添加display: table-cell;宽度:1%;到您的表格单元格元素。

.table-cell { display: table-cell; width: 1%; padding: 4px; border: 1px solid #efefef; } <div class="table"> <div class="table-cell">one</div> <div class="table-cell">two</div> <div class="table-cell">three</div> <div class="table-cell">four</div> </div> <div class="table"> <div class="table-cell">one</div> <div class="table-cell">two</div> <div class="table-cell">three</div> <div class="table-cell">four</div> </div> <div class="table"> <div class="table-cell">one</div> </div>


另一个建议是使用flexbox而不是完全使用表格。这当然是一个“现代浏览器”的事情,但拜托,这是2016年;)

至少对于那些现在正在寻找答案的人来说,这可能是另一种解决方案,因为最初的帖子是在2010年发布的。

这里有一个很好的指南:https://css-tricks.com/snippets/css/a-guide-to-flexbox/

.table { border: 1px solid red; padding: 2px; max-width: 300px; display: flex; flex-flow: row wrap; } .table-cell { border: 1px solid blue; flex: 1 30%; } .colspan-3 { border: 1px solid green; flex: 1 100%; } <div class="table"> <div class="table-cell"> row 1 - cell 1 </div> <div class="table-cell"> row 1 - cell 2 </div> <div class="table-cell"> row 1 - cell 3 </div> <div class="table-cell colspan-3"> row 2 - cell 1 (spans 3 columns) </div> </div>


提供一个最新的答案:今天最好的方法是使用css网格布局,像这样:

.container {
  display: grid;
  grid-template-columns: 1fr 1fr 1fr;
  grid-template-rows: auto;
  grid-template-areas: 
    "top-left top-middle top-right"
    "bottom bottom bottom"
}

.item-a {
  grid-area: top-left;
}
.item-b {
  grid-area: top-middle;
}
.item-c {
  grid-area: top-right;
}
.item-d {
  grid-area: bottom;
}

以及HTML

<div class="container">
  <div class="item-a">1</div>
  <div class="item-b">2</div>
  <div class="item-c">3</div>
  <div class="item-d">123</div>
</div>

如果你来这里是因为你必须打开或关闭colspan属性(比如移动布局):

复制<td>,只显示所需colspan的值:

table.colspan--on td.single { display: none; } table.colspan--off td.both { display: none; } <!-- simple table --> <table class="colspan--on"> <thead> <th>col 1</th> <th>col 2</th> </thead> <tbody> <tr> <!-- normal row --> <td>a</td> <td>b</td> </tr> <tr> <!-- the <td> spanning both columns --> <td class="both" colspan="2">both</td> <!-- the two single-column <td>s --> <td class="single">A</td> <td class="single">B</td> </tr> <tr> <!-- normal row --> <td>a</td> <td>b</td> </tr> </tbody> </table> <!-- that's all -->   <!-- stuff only needed for making this interactive example looking good: --> <br><br> <button onclick="toggle()">Toggle colspan</button> <script>/*toggle classes*/var tableClasses = document.querySelector('table').classList; function toggle() { tableClasses.toggle('colspan--on'); tableClasses.toggle('colspan--off'); } </script> <style>/* some not-needed styles to make this example more appealing */ td {text-align: center;} table, td, th {border-collapse: collapse; border: 1px solid black;}</style>


我已经取得了一些成功,尽管它依赖于一些属性来工作:

表布局:固定 border-collapse:独立

以及单元格宽度,即4个单元格的宽度为25%:

.div-table-cell, * { box-sizing: border-box; } .div-table { display: table; border: solid 1px #ccc; border-left: none; border-bottom: none; table-layout: fixed; margin: 10px auto; width: 50%; border-collapse: separate; background: #eee; } .div-table-row { display: table-row; } .div-table-cell { display: table-cell; padding: 15px; border-left: solid 1px #ccc; border-bottom: solid 1px #ccc; text-align: center; background: #ddd; } .colspan-3 { width: 300%; display: table; background: #eee; } .row-1 .div-table-cell:before { content: "row 1: "; } .row-2 .div-table-cell:before { content: "row 2: "; } .row-3 .div-table-cell:before { content: "row 3: "; font-weight: bold; } .div-table-row-at-the-top { display: table-header-group; } <div class="div-table"> <div class="div-table-row row-1"> <div class="div-table-cell">Cell 1</div> <div class="div-table-cell">Cell 2</div> <div class="div-table-cell">Cell 3</div> </div> <div class="div-table-row row-2"> <div class="div-table-cell colspan-3"> Cor blimey he's only gone and done it. </div> </div> <div class="div-table-row row-3"> <div class="div-table-cell">Cell 1</div> <div class="div-table-cell">Cell 2</div> <div class="div-table-cell">Cell 3</div> </div> </div>

此外,应用display:table-header-group或table-footer-group是将'row'元素跳转到'table'的顶部/底部的便捷方法。


CSS属性“column-count”、“column-gap”和“column-span”可以做到这一点,使伪表的所有列保持在相同的包装器中(HTML保持漂亮和整洁)。

唯一需要注意的是,您只能定义1列或所有列,而且列-span在Firefox中还不能工作,因此需要一些额外的CSS来确保它能够正确显示。 https://www.w3schools.com/css/css3_multiple_columns.asp

.split-me { -webkit-column-count: 3; -webkit-column-gap: 0; -moz-column-count: 3; -moz-column-gap: 0; column-count: 3; column-gap: 0; } .cols { /* column-span is 1 by default */ column-span: 1; } div.three-span { column-span: all !important; } /* alternate style for column-span in Firefox */ @-moz-document url-prefix(){ .three-span { position: absolute; left: 8px; right: 8px; top: auto; width: auto; } } <p>The column width stays fully dynamic, just like flex-box, evenly scaling on resize.</p> <div class='split-me'> <div class='col-1 cols'>Text inside Column 1 div.</div> <div class='col-2 cols'>Text inside Column 2 div.</div> <div class='col-3 cols'>Text inside Column 3 div.</div> <div class='three-span'>Text div spanning 3 columns.</div> </div> <style> /* Non-Essential Visual Styles */ html * { font-size: 12pt; font-family: Arial; text-align: center; } .split-me>* { padding: 5px; } .cols { border: 2px dashed black; border-left: none; } .col-1 { background-color: #ddffff; border-left: 2px dashed black; } .col-2 { background-color: #ffddff; } .col-3 { background-color: #ffffdd; } .three-span { border: 2px dashed black; border-top: none; text-align: center; background-color: #ddffdd; } </style>


我来这里是因为目前WordPress表块不支持colspan参数,我想我会用CSS替换它。这是我的解决方案,假设列的宽度相同:

table { width: 100%; } table td { width: 50%; background: #dbdbdb; text-align: center; } table tr:nth-child(2n+1) { position:relative; display:block; height:20px; background:green; } table tr:nth-child(2n+1) td { position:absolute; left:0; right:-100%; width: auto; top:0; bottom:0; background:red; text-align:center; } <table> <tr> <td>row</td> </tr> <tr> <td>cell</td> <td>cell</td> </tr> <tr> <td>row</td> </tr> <tr> <td>cell</td> <td>cell</td> </tr> </table>
