如何在结构不连接时用css近似表格布局 [英] How to approximate table layout with css when structure is disjointed

问题描述

我有一些HTML，我想使用display：table css属性来控制。不幸的是，我实际上不能改变HTML（或JS），只有CSS（长故事）。这是一个问题，因为现有HTML的结构导致表布局的麻烦。以下是HTML和CSS的简化版本：

I have some HTML which I want to use display: table css attributes to control. Unfortunately, I cannot actually change the HTML (or JS either), only the CSS (long story). This is a problem, because the structure of the existing HTML is causing trouble for the table layout. Here is a simplified version of the HTML and CSS:

<style>
    .like-table { display: table;}
    .like-tr { display: table-row;}
    .like-th { display: table-cell; border: 1px solid gray;}
    .useless-div-1 { }
    .useless-div-2 { }
    .like-td { display: table-cell; border: 1px solid gray;}
</style>
<div class="like-table">
    <div class="like-tr">
        <div class="like-th">1</div>
        <div class="like-th">22</div>
        <div class="like-th">3</div>
    </div>
    <div class="useless-div-1"><div class="useless-div-2">
        <div class="like-tr">
            <div class="like-td">111</div>
            <div class="like-td">2</div>
            <div class="like-td">3</div>
        </div>
        <div class="like-tr">
            <div class="like-td">11</div>
            <div class="like-td">2</div>
            <div class="like-td">333</div>
        </div>
    </div></div>
</div>

很不幸，这会使标题和正文列的宽度不同：

Sadly, this renders the header and body columns width different widths:

>

如果我删除useless-div- *打开和关闭标签：

If I remove the "useless-div-*" open and closing tags:

<div class="like-table">
    <div class="like-tr">
        <div class="like-th">1</div>
        <div class="like-th">22</div>
        <div class="like-th">3</div>
    </div>
    <div class="like-tr">
        <div class="like-td">111</div>
        <div class="like-td">2</div>
        <div class="like-td">3</div>
    </div>
    <div class="like-tr">
        <div class="like-td">11</div>
        <div class="like-td">2</div>
        <div class="like-td">333</div>
    </div>
</div>

然后，它会渲染精细，对齐标题和正文列宽度：

Then it renders fine, aligning header and body column widths:

>

所以，有什么我可以做的CSS，将导致第一组HTML的行为像第二个？记住我不能修改HTML或JavaScript - 只有CSS ！请不要问为什么...

So, is there anything I can do to the CSS that will cause the first set of HTML to behave like the second? Remember I cannot modify the HTML or JavaScript -- only the CSS! Please do not ask why...

推荐答案

因为你要包装 table-row 元素 useless-div ，你可以简单地设置 display useless-div 至 table-row-group ：

Since you're wrapping table-row elements by useless-div, you could simply set display property of useless-div to table-row-group:

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

在CSS表布局中，所有元素应遵循相同的结构属性。

In CSS table layouts, all elements should follow the same structural properties.

以下是 JSBin演示 。

Here is the JSBin Demo.

在 之后，我抓住了我的头5个小时，我意识到这是不可能通过当前的方式来处理这个。

After scratching my head for the past 5 hours over this, I realized that it's impossible to handle this by the current way.

决定编写新的样式来创建一个灵活的CSS表。但我首先要提到几个事情：

So, I decided to write new styles to create a flexible CSS table. But I should mention a few things at first:

• 要保持列垂直排列，需要为单元格设置特定宽度。 li>
  
• 在以下示例中，我设置边框以更好地显示表。因为这样，我使用 box-sizing 属性来强制浏览器计算每个单元格的宽度，包括其填充和边框。如果您不需要 border ，请删除它和 border-box 属性。

• To keep the columns aligned vertically, setting a specific width to cells is required.
• In the following example, I set borders to display the table better. because of that, I used box-sizing property to force browser to calculate the width of each cell including its padding and border. If you don't need border, remove it and the border-box property as well.

.like-table {
  width: 400px;    /* You could declare a specific width. Your choice */
  margin: 0 auto;
}

.like-th, .like-td {
  float: left;    /* <--  Float the cells to stick together                    */
  width: 33.33%;  /* <--  I applied the same width on each cell.               */
  /* I've explained how to set specific width for each column in the following */

  border: 1px solid gray;          /* Add border around each cell */

  -webkit-box-sizing: border-box;  /* Force browser to calculate width+borders */
  -moz-box-sizing: border-box;
  box-sizing: border-box;
}

.like-tr:after { /* Clearfix hack */
  content: ' ';
  font: 0/0 a;
  display: block;
  clear: both;
}

注意： （左+中心+右），首先在每个单元格上设置 width 以下选择器覆盖左和右列的应用宽度：

Note: To apply specific width on each column (left + center + right), First set a width on each cell as I did at above, then use the following selectors to override the applied width for left and right columns:

.like-table .like-td:first-child, /* Selectors for the left column */
.like-table .like-th:first-child { 
  width: 100px;     /*  <-- Override the width for the left column */
  border-right: 0;  /* You might also want to remove right borders */
}

.like-table .like-td:last-child,  /* Selectors for the right column */
.like-table .like-th:last-child {
  width: 100px;      /* <-- Override the width for the right column */
  border-left: 0;    /* You might also want to remove left borders  */
}
