html - 根据 Angular 字大小自动调整行的大小

Question

我正在尝试创建一个 HTML 表格，我希望我的标题旋转 45 度。

我在网上找到了一些可以使用的示例。但是，标题行高度不会根据输入的文本调整大小。文本只是包裹在单元格中。

如何让行根据倾斜的文本自动调整单元格高度？

我的代码

HTML

  <div class="scrollable-table">
    <table class="table table-striped table-header-rotated">
      <thead>
        <tr>
          <!-- First column header is not rotated -->
          <th></th>
          <!-- Following headers are rotated -->
          <th class="column criterion rotate-45" ><div><span>Column header 1</span></div></th>
          <th class="column criterion rotate-45" ><div><span>Column header 2</span></div></th>
        </tr>
      </thead>
      <tbody>
        <tr>
          <th class="row-header">Row header 1</th>
          <td><input checked="checked" name="column1[]" type="radio" value="row1-column1"></td>
          <td><input checked="checked" name="column2[]" type="radio" value="row1-column2"></td>
        </tr>
        <tr>
          <th class="row-header">Row header 2</th>
          <td><input name="column1[]" type="radio" value="row2-column1"></td>
          <td><input name="column2[]" type="radio" value="row2-column2"></td>
        </tr>
        <tr>
          <th class="row-header">Row header 3</th>
          <td><input name="column1[]" type="radio" value="row3-column1"></td>
          <td><input name="column2[]" type="radio" value="row3-column2"></td>
        </tr>
      </tbody>
    </table>
  </div>
</body>

CSS

.table-header-rotated th.row-header{
  width: auto;
}

.table-header-rotated td{
  width: 40px;
  border-top: 1px solid #dddddd;
  border-left: 1px solid #dddddd;
  border-right: 1px solid #dddddd;
  vertical-align: middle;
  text-align: center;
}

.table-header-rotated th.rotate-45{
  height: 80px;
  width: 40px;
  min-width: 40px;
  max-width: 40px;
  position: relative;
  vertical-align: bottom;
  padding: 0;
  font-size: 12px;
  line-height: 0.8;
}

.table-header-rotated th.rotate-45 div{
  position: relative;
  top: 0px;
  left: 40px; /* 80 * tan(45) / 2 = 40 where 80 is the height on the cell and 45 is the transform angle*/
  height: 100%;
  -ms-transform:skew(-45deg,0deg);
  -webkit-transform:skew(-45deg,0deg);
  transform:skew(-45deg,0deg);
  overflow: hidden;
  border-left: 1px solid #dddddd;
  border-right: 1px solid #dddddd;
  border-top: 1px solid #dddddd;
}

.table-header-rotated th.rotate-45 span {
  -ms-transform:skew(45deg,0deg) rotate(315deg);
  -webkit-transform:skew(45deg,0deg) rotate(315deg);
  transform:skew(45deg,0deg) rotate(315deg);
  position: absolute;
  bottom: 30px; /* 40 cos(45) = 28 with an additional 2px margin*/
  left: -25px; /*Because it looked good, but there is probably a mathematical link here as well*/
  display: inline-block;
  width: 85px; /* 80 / cos(45) - 40 cos (45) = 85 where 80 is the height of the cell, 40 the width of the cell and 45 the transform angle*/
  text-align: left;
  /* white-space: nowrap; *//*whether to display in one line or not*/
}

编辑我做了一个基于 Jquery 的解决方案。我根据文本字符串的像素长度计算行高。在我的案例中，我发现的其他一些值可能只是静态的。请看我的 Fiddle

您需要添加 white-space:nowrap; 到您的页眉样式

.table-header-rotated th.rotate-45 {
    height: 80px;
    width: 40px;
    min-width: 40px;
    max-width: 40px;
    position: relative;
    vertical-align: bottom;
    padding: 0;
    font-size: 12px;
    line-height: 0.8;
    white-space: nowrap;
}
