【问题描述】：
在下面的 asp.net 示例 webform 应用程序中（下面的标记和代码以及示例数据），我使用 webmethod 将 JQuery 工具提示应用到具有 5 列的 gridview 中的一个单元格 - 要求是“他们想要滚动网格视图的网格视图上没有分页。我的示例中的数据源包含从 A 到 Z 的 26 行。我将包含 gridview 的 div 的高度设置为 300px，以便获得一个滚动条来说明我的问题。工具提示工作正常，除了 1) 将鼠标悬停在工具提示的单元格（我的示例中的第 1 列）上时，行扩展并且该行的单元格被推到第 1 列单元格的右侧 - 就像在之后添加了一个幻像单元格单元格（1）。并且... 2）如果您将鼠标悬停在第 1 列中的工具提示单元格上时，如果您滚动到 gridview 的底部 - 朝向 zzz 行（其中 aaa 到 fff 行不可见），gridview 行会像 j 行一样跳回.
如何防止这种情况发生——行的跳跃？将鼠标悬停在工具提示单元格上时，是否可以防止单元格被推到右侧？防止幻影细胞出现？如何解决这个/这些问题？这是 JQuery 问题还是 CSS 问题？
