/* ===== 表格 — v3 彻底修复 =====
   ═══════════════════════════════════════════════════
   核心思路：
   1. table 用 min-width:100% + width:max-content
      → 内容少时撑满容器，多时自然超出触发横向滚动
   2. table-wrap 设 overflow-x:auto → 产生横向滚动条
   3. 父链 card/main-area 均不裁切溢出 (overflow:visible / min-width:0)
   4. 各列设置合理的 min-width，防止挤压
