* 隐藏表格的横向滚动条，按住鼠标左键横向拖动即可查看后面的字段。
* 通过 document 事件委托全局生效，所有 el-table 自动支持，无需逐页绑定。
*
* 手感优化：
* - 文本选中已在全局样式中禁用（user-select: none），拖拽过程不会再误选文字
* - 位移以横向为主且超过阈值才触发滚动，轻微手抖、普通点击、纵向拖拽（如行排序）不受影响
* - 光标仅在真正拖动时变为抓手，平时保持默认
* - 拖拽结束（确实发生了滚动）后屏蔽本次 click，避免误触发行点击、复选框等
* 实现要点（全面优化）：
* - 采用 Pointer Events + setPointerCapture：按下瞬间把指针捕获到滚动容器上，
* 之后无论光标移动到固定列、表格下方还是窗口外，移动事件都不会中断，真正"跟手"。
* - requestAnimationFrame 合并每帧滚动，避免高频事件造成卡顿/闪烁。
* - 横向位移超过阈值即触发，允许轻微斜向/弧线；仅当纵向明显占优时才不触发，
* 保留普通点击与纵向拖拽（如行排序）的区分。
* - 拖拽期间整页锁定光标与文本选中，光标保持默认箭头，不闪变为抓手/手型。
