扩展行

Question

背景
我已经将一个带有折叠文本对象的简单表放在一起，当单击它时，会展开以显示与标题/标题相关的更多详细信息。

代码： JSFiddle

问题
当行元素展开时，它会强制内容与其标题相同的列，而不是占据整行的宽度以显示所有三列下面的文本。与此类似：

Normal State / Collapsed:
 -----------------------------------------
| > Title to expand   |    x    |    ✓    |
 -----------------------------------------

Intended State / Expanded:
 -----------------------------------------
| ⌄ Title to expand   |    x    |    ✓    |
|   Item explanation - spans entire width |
 -----------------------------------------

Not intended when expanded (problem):
 -----------------------------------------
| ⌄ Title to expand   |    x    |    ✓    |
|   Item explanation -                    |
|   spans entire width                    |
 -----------------------------------------
or
 -------------------------------------------------------------
| ⌄ Title to expand                       |    x    |    ✓    |
|   Item explanation - spans entire width                     |
 -------------------------------------------------------------

预期结果
上面（中间）图显示了最终结果应该是什么样子。我知道使用display: none;来隐藏行，但是，我不希望内容在一个单独的行中，而是“扩展”它所在的那个。

问题
如何以解释填充3列下方整行的宽度的方式展开项目？这里有任何帮助，我相信那里有一些CSS专家。我希望这些例子能说清楚，如果您需要更多信息，请告诉我。我总是非常乐意详细说明。欢呼声。

将图标放在同一个td中，然后使用一些margin-right将它们向右浮动：

@import url("https://fonts.googleapis.com/css?family=Source+Sans+Pro:300,300italic,400,600");
@import url("https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css");
