html - <table> 中的 Flex CSS 属性在 IE 和 Firefox 上不起作用

Question

我正在寻找一种解决方案，如何使 Flex 属性在所有三种浏览器(IE、Firefox 和 Chrome)的 table 组件上工作。

以下代码仅适用于 Chrome(即使添加了 -ms- 和 -webkit- 前缀):

table {
  background-color: white;
}
.child {
  padding: 5px;
  margin: 5px;
  background-color: #eee;
  border: 3px solid;
}
.container {
  padding: 2px;
  background-color: yellow;
  display: -ms-flexbox;
  display: -webkit-flex;
  display: flex;
  -webkit-flex-direction: row;
  -ms-flex-direction: row;
  flex-direction: row;
  -webkit-flex-wrap: wrap;
  -ms-flex-wrap: wrap;
  flex-wrap: wrap;
  -webkit-justify-content: space-between;
  -ms-flex-pack: justify;
  justify-content: space-between;
  -webkit-align-content: center;
  -ms-flex-line-pack: center;
  align-content: center;
  -webkit-align-items: stretch;
  -ms-flex-align: stretch;
  align-items: stretch;
}
.child.one {
  color: green;
  -webkit-order: 1;
  -ms-flex-order: 1;
  order: 1;
}
.child.two {
  color: purple;
  -webkit-order: 2;
  -ms-flex-order: 2;
  order: 2;
  flex-shrink: 0;
}
.child.three {
  color: red;
  -webkit-order: 3;
  -ms-flex-order: 3;
  order: 3;
}

<table style="width:100%">
  <tbody>
    <tr class="container">
      <td class="child one" align="left">
        One
      </td>
      <td class="child two" align="center">
        Two.
        <br>Lorem ipsum
        <br>dolor sit amet
        <br>This is a bit longer line
      </td>
      <td class="child three" align="right">
        Three
      </td>
    </tr>
  </tbody>
</table>

这似乎是由于每个 .child 元素在默认情况下都是 display: table-cell;(预期这些确实是表格单元格!)。

在 Chrome 中，当您在 .container 上使用 flexbox 模型时，.child 元素会自动转换为启用 flexbox 的 display: block;上类。

在 Firefox 和 IE 中，.child 元素保留为 display: table-cell;。

CSS Flexible Box Layout Module 的最新 W3C 草案指出:

The display value of a flex item is blockified: if the specified display of an in-flow child of an element generating a flex container is an inline-level value, it computes to its block-level equivalent. (See CSS2.1§9.7 [CSS21] and CSS Display [CSS3-DISPLAY] for details on this type of display value conversion.)

flex 元素 ( https://drafts.csswg.org/css-flexbox-1/#flex-items)

这表明应将 flex 元素更改为其 block-level equivalent (如果它还不是 block 级元素)。

草案更进一步指出:

Some values of display normally trigger the creation of anonymous boxes around the original box. If such a box is a flex item, it is blockified first, and so anonymous box creation will not happen. For example, two contiguous flex items with display: table-cell will become two separate display: block flex items, instead of being wrapped into a single anonymous table.

在这种情况下，这似乎是 Chrome 正在做的事情，但 IE 和 Firefox 不是。匿名表的存在以及 .child 元素未被 block 化的事实似乎是导致该行为的原因。

要在 Chrome、IE 和 Firefox 中获得相同的结果:

• 添加display: block;到.child
• 为确保 .child 元素在 IE 中正确包装，将 display: block; 添加到 table 和 tbody

table {
  background-color: white;
  display: block; /*Required for wrap to work correctly in IE*/
}
tbody {
  display: block; /*Required for wrap to work correctly in IE*/
}
.child {
  padding: 5px;
  margin: 5px;
  background-color: #eee;
  border: 3px solid;
  display: block;
}
.container {
  padding: 2px;
  background-color: yellow;
  display: -ms-flexbox;
  display: -webkit-flex;
  display: flex;
  -webkit-flex-direction: row;
  -ms-flex-direction: row;
  flex-direction: row;
  -webkit-flex-wrap: wrap;
  -ms-flex-wrap: wrap;
  flex-wrap: wrap;
  -webkit-justify-content: space-between;
  -ms-flex-pack: justify;
  justify-content: space-between;
  -webkit-align-content: center;
  -ms-flex-line-pack: center;
  align-content: center;
  -webkit-align-items: stretch;
  -ms-flex-align: stretch;
  align-items: stretch;
}
.child.one {
  color: green;
  -webkit-order: 1;
  -ms-flex-order: 1;
  order: 1;
}
.child.two {
  color: purple;
  -webkit-order: 2;
  -ms-flex-order: 2;
  order: 2;
  flex-shrink: 0;
}
.child.three {
  color: red;
  -webkit-order: 3;
  -ms-flex-order: 3;
  order: 3;
}

<table style="width:100%">
  <tbody>
    <tr class="container">
      <td class="child one" align="left">
        One
      </td>
      <td class="child two" align="center">
        Two.
        <br>Lorem ipsum
        <br>dolor sit amet
        <br>This is a bit longer line
      </td>
      <td class="child three" align="right">
        Three
      </td>
    </tr>
  </tbody>
