旋转表头

Question

我试图-60°通过向rotated-text每个标题添加一个类来旋转引导程序 4 表中的标题：

<table class="table table-hover">
    <thead class="text-left">
        <th class="rotated-text" scope="col">Col 1 header</th>
    </thead>

    [...]

.rotated-text {
    -webkit-transform: rotate(-60deg);
    -ms-transform: rotate(-60deg);
    transform: rotate(-60deg);
    font-size: larger;
}

但是，这会导致标题被换行，并且文本并未真正与标题/行边框左对齐（请参见下面的代码段）。我怎样才能解决这个问题？

<table class="table table-hover">
    <thead class="text-left">
        <th class="rotated-text" scope="col">Col 1 header</th>
    </thead>

    [...]

.rotated-text {
    -webkit-transform: rotate(-60deg);
    -ms-transform: rotate(-60deg);
    transform: rotate(-60deg);
    font-size: larger;
}

Answer 1

啊。这里的窍门是把标题文字的<span>嵌套的<div>（见本文章）：

th.rotated-text {
    height: 140px;
    white-space: nowrap;
    padding: 0 !important;
}

th.rotated-text > div {
    transform:
        translate(13px, 0px)
        rotate(310deg);
    width: 30px;
}

th.rotated-text > div > span {
    padding: 5px 10px;
}
