如何垂直居中对齐表格内的图标 header

[英]How to vertically center align icon inside table header

我有一个动态表,列和行的动态编号......在表 header 中,我需要修复排序图标垂直居中......即使表 header 文本大小是动态的并且行数不断增长......如何垂直对齐在文本大小不断增加的同时排序图标?

小提琴手

<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;
}

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,两个对齐的元素都需要具有相等的垂直paddingbordermargin


使用您刚刚添加的示例,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;
}

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jsfiddle

这个怎么样?

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

.icon-right {
  position: absolute;
  top: 50%;
  right: 0;
  margin-top:-10px;
}

试试这个

 .header-container {
        height: 100%;
        display: flex;
        align-items: center;
        justify-content: space-between;
    }

试试这些属性我觉得它对你有用。

.header-container {
  display: flex;
  align-items: center;
  justify-content: space-between;
}

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

 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; } .header-text { color: #000000; font-weight: normal; } .header-text { width: 90%; float: left; text-align: start; letter-spacing: 0; text-align: left; } .sort-icon { float: right !important; clear: right; height: 1px !important; } .header-container { display: flex; align-items: center; justify-content: space-between; } .icon-right { margin-top: -15px; }

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;
}

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?

我不知道如何使用绝对 position 对我有用!

<th>
 Title <span class="sort-icon"><i class="fa fa-sort"></i></span>
</th>
.sort-icon {
    position: absolute;
}
