/* 窄屏表格：七列在 390px 里放不下，会挤成"陈/琪""DMT-/16P"这种一字一行。
   手机上只留 类型 / 标题 / 指派 / 状态 四列，机型提出更新先不显示 ——
   点进详情页全都有，列表页首要任务是"能一眼扫过去"。

   注意 `table-layout: fixed` 是必须的，不能只写 display:none 就完事：
   自动布局下浏览器按"最小内容宽度"分配空间，标题允许 break-word ⇒ 最小宽度
   正好是 1 个字，而状态列里两个 tag 是 nowrap ⇒ 最小宽度很大。结果标题被压成
   一字一行、整个表格还横向溢出。改成固定布局并给三列写死宽度，标题拿走剩下的。 */
