以下代码基于How to set focus to cell which was clicked to start inline edit in jqgrid
的回答用于将焦点置于单击的单元格上，以便单击即可开始内联编辑此单元格。
如果jqgrid是宽的，以便显示水平滚动条并且单击最右边的列，则jqgrid会滚动到最左边的列，之后会滚动回到单击的列。
这会导致令人不快的闪烁视觉效果。 如何删除此闪烁？
要重现，请在Chrome中打开下方的页面，向右滚动并单击“数量”列。 编辑开始前网格闪烁。 如何删除此闪烁？
可以在此滚动期间关闭屏幕更新，放置所有网格单元格 最初编辑模式还是其他想法？

我不确定我是否正确理解了这个问题。 editRow支持从jqGrid 4.7开始的focusField选项（请参阅the documentation）。它也可以在免费的jqGrid中使用。值focusField: false将阻止将焦点设置到第一个可编辑列。您通常可以删除PutFocus功能并将其替换为focusField: colName（名称colName似乎不是最好的，因为它更多iCol），其中值focusField应该是行中列的编号。
