垂直旋轉的表格標題，居中+底部對齊，跨瀏覽器

Question

我的表格帶有旋轉標題，在 Chrome 中看起來符合預期，但在 Firefox 中卻不是。

Chrome v108（垂直底部，水平中間）✅

Firefox v107（垂直中間，水平右）❌

#

如何讓它們跨瀏覽器工作，以便它們垂直旋轉、垂直位於單元格底部、水平居中並佔用最小寬度？

我使用的程式碼對此答案進行了稍微修改，以使其在 Chrome 中工作：

table { border-collapse:collapse; font-family:sans-serif }
thead th {
    /* Rotate vertical: https://stackoverflow.com/a/47245068 */
    -ms-writing-mode:tb-rl;
    -webkit-writing-mode:vertical-lr;
    writing-mode:vertical-rl;
    transform:rotate(180deg);
    vertical-align:middle;
    text-align:left;
    padding:0.5em 0 0 0;
    opacity:0.5;
    font-size:90%;
}
tbody th { text-align:right; padding-right:0.5em }
tbody td { text-align:center; padding:0 0.2em }
.yes { font-weight:bold; color:#060 }
.maybe { color:#440 }
.no  { color:#500 }

<table><thead><tr>
    <th></th>
    <th class="yes">yes</th>
    <th class="maybe">maybe</th>
    <th class="no">no</th>
    <th>who?</th>
</tr></thead><tbody><tr>
    <th>Fri, Dec 9, 12pm</th>
    <td class="yes">2</td><td class="maybe">1</td><td class="no">1</td>
    <td><button>≡</button></td>
</tr><tr>
    <th>Wed, Dec 14, 12pm</th>
    <td class="yes">4</td><td class="maybe">0</td><td class="no">0</td>
    <td><button>≡</button></td>
</tr><tr>
    <th>Fri, Dec 16, 12pm</th>
    <td class="yes">0</td><td class="maybe">0</td><td class="no">1</td>
    <td><button>≡</button></td>
</tr></tbody></table>

這似乎對我有用，在 Chrome、Firefox 和 iOS Safari 上進行了測試：

thead th {
  vertical-align: bottom;
  text-align:     center;
  width:          0.5em;
  min-width:      0.5em;
  padding:        0;
}
thead th span {
  writing-mode: vertical-lr;
  transform:    rotate(180deg);

  /* slight horizontal offset to suit tastes */
  position:relative; left:-2px;
}

/* need following (or explicit width) or else the */
/* cells in the rows will force wrap every word   */
tbody th { white-space:nowrap }

/*************** unrelated formatting ***************/
table { border-collapse:collapse; margin:1em auto }
thead th { font-size:90% }
thead th span { opacity:0.5 }
th, td { vertical-align:middle; padding:0 0.5em }
th { text-align:right; font-weight:normal }

.yes { color:#090; font-weight:bold }
.maybe { color:#660 }
.no  { color:#600 }

tr > * { border-bottom:1px solid rgba(0,0,0,0.2)}
tr:last-child > * { border-bottom: 0 }

	yes	maybe	no	who?
Fri, Dec 9, 12pm	2	1	1	≡
Wed, Dec 14, 12pm	4	0	0	≡
Fri, Dec 16, 12pm	0	0	1	≡
