不可能将列动态添加到jqGrid.您必须使用colModel再创建一列来重新创建整个网格.如果使用单独的colNames，则数组的大小也必须增加.例如，您可以使用GridDestroy销毁现有网格.您实际上可以像往常一样绑定一个额外的列，但是可以在运行时使用jquery显示/隐藏它们.因此，您可以只添加一列，然后根据需要使用.
It is not possible to add a column to the jqGrid dynamically. You have to recreate the whole grid with colModel having one column more. If you use separate colNames, then the size of the array have to be increased too. You can use GridDestroy for example to destroy the existing grid. you can actually bind an extra column as normal but you can show/hide them at runtime using jquery. So you could just add a column and hide/show it as per your requirement using .
$("#grid").showCol("column_name");
$("#grid").hideCol("column_name");
