         “操作”列此前留了140px但行内只有一个小圆形展开箭头（真正的减仓/清仓按钮在展开面板里），
         白白挤占“名称”列的1fr空间，导致标的名称在桌面端被截断（手机版是纵向堆叠布局不受影响）。
         这里把code/qty/cost/date/action几列收紧，并给名称列一个minmax保底宽度。
         “实仓→目标”列按实测最长内容定宽：“实仓 100.00% → 目标 100.00%”在12px等宽字体下约182px，
         之前只给106px，连常规的“实仓 10.20% → 目标 10.00%”（约168px）都放不下，
         之前误以为只有“仓位待今日扫描确认”这个占位文案（约108px）超宽——实际这一列本身就没给够，
         从qty/cost/date几个明显有富余的定宽列（原72/84/100px，实际内容只需约42/35/70px）挪出空间补给它。 */
