/* ==========================================================================
   表格通用层：横向滚动 + 操作列吸附
   --------------------------------------------------------------------------
   为什么需要：
     .data-card { overflow:hidden } —— 里面的表格一旦超宽就被直接裁掉，
     右侧「操作」列既看不到也点不到。而 <table> 默认 table-layout:auto 时
     **td 上的 max-width 会被浏览器忽略**，配上 white-space:nowrap 的长 URL，
     单列 min-content 就能到 500px+，整表轻易超过容器。
   所以两手都要：① 给表格包一层可横向滚动的 .table-wrap；
              ② 把「操作」列 sticky 在右侧，滚到哪都够得着。
