如何在表头中垂直居中对齐图标

Question

我有一个动态表，动态没有列和行...在表头，我需要垂直中心修复排序图标..甚至表头文本大小是动态的，没有行保持增长...如何垂直对齐文本大小不断增加时排序图标？

jsfiddle

<table style="width:100%">
  <tr>
    <th><div class='filter-container header-container'> <div class='header-text'>  Firstname Firstname Firstnam eFirstnam eFirstname Firstname Firstname Firstname Firstname</div><div class='icon-right'> <span    class= "fa fa-sort-asc fa-lg sort-icon "></span><span   class= "fa fa-sort-desc fa-lg sort-icon  "></span></div></div></th>
    <th>Lastname</th> 
    <th>Age</th>
  </tr>
  <tr>
    <td>Jill</td>
    <td>Smith</td>
    <td>50</td>
  </tr>
  <tr>
    <td>Eve</td>
    <td>Jackson</td>
    <td>94</td>
  </tr>
  <tr>
    <td>John</td>
    <td>Doe</td>
    <td>80</td>
  </tr>
</table>

CSS：

table, th, td {
  border: 1px solid black;
  border-collapse: collapse;
}

th, td {
  padding: 5px;
}

.filter-container {
  width: 100%;
  height: 100%;
  position: relative;
  padding: 0px !important;
  margin: 0px !important;
}

.header-container {
  height: 100%;
  vertical-align: middle;
  text-align: center;
}

.header-text {
  font-size: 22px;
  line-height: 24px;
  color: #000000;
  font-weight: normal;
  width: 90%;
  float: left;
  letter-spacing: 0;
  text-align: left;
}

.sort-icon {
  float: right !important;
  clear: right;
  height: 1px !important;
}

Answer 1

使用整个表头单元格内容的包装器。在其中，使用两个元素。文字和图标：

<th>
  <div class="aligner">
    <div class="text">any text here can be as long as you want</div>
    <div class="icon">your icon here</div>
  </div>
</th>

并使用：

th .aligner {
  display: flex;
  align-items: center;
}

显然，两个对齐的元素需要具有相等的垂直padding，border和margins。

使用刚刚添加的示例，这是一个启动器：https://jsfiddle.net/websiter/h94yen82/

我删除了分拣机的样式并添加了：

.header-container {
  justify-content: space-between;
}
.sort-icon {
  display: flex;
  flex-direction: column;
  justify-content: center;
  height: 0;
}

Answer 2

快速/简单修复，将其添加到.icon-right：

.icon-right {
    ...
    top: calc(50% - 8px);
    position: relative;
}

编辑

由于您要将其应用于所有列，请尝试以下操作：

.icon-right {/* Add this new class */
    top: calc(50% - 8px);
    position: absolute;
    right: 5px;
}

th {/* Add this new class */
    position: relative;
}

.filter-container {
    ...
    /*position: relative;*/ /* remove this line */
    ...
}

试试吧jsfiddle。

试试这些属性我觉得它对你有用。

.header-container {

.icon-right {
  margin-top: -15px;
}

table, th, td {
  border: 1px solid black;
  border-collapse: collapse;
}
th, td {
  padding: 5px;
}

.filter-container {

.header-text {
	width: 90%;
	float: left;
	text-align: start;
	letter-spacing: 0;
	text-align: left;

.sort-icon {

 .header-container {

        align-items: center;
        justify-content: space-between;
    }

.icon-right {
    margin-top: -15px;
}

Answer 6

你可以使用transform来使div垂直对齐

.icon-right{
  top: 40%;
  transform: translateY(-40%);
  position: relative;
  line-height: 1.8em;
}

Answer 7

几乎答案设置两个图标的高度是0px或1px使两个图标差不多，所以无法点击排序。我认为你应该使用另一个图标（或图像）宽度距离到顶部和底部理性（如fa-caret）。这个怎么样？
