Question

我正在尝试使用this文章修复JQGrid的冻结列的行高。我已经尝试了几天以来的工作。当网格加载正确时，我在某种程度上取得了成功，但在重新调整列标题时仍然存在问题。

我对原始代码所做的修改只是将以下条件添加到fixPositionsOfFrozenDivs函数中。

if（this.grid！== undefined）{ }

重现问题的步骤：

加载网格。
尝试减小列标题的宽度，以便重新调整冻结列的高度。

以下是我的代码：

$.jgrid.no_legacy_api = true;
$.jgrid.useJSON = true;

这是重新调整列标题大小时的显示方式。

我在这里做错了什么？

试试the following demo。它有同样的问题吗？如果你可以在这里重现问题那么请描述完整的测试用例（如何逐步重现问题）。

更新：您发布的代码似乎是旧代码与我的演示代码的组合。问题$grid = $("#list")中存在问题。我在演示中使用了id="list"的网格，但您使用了id="BudgetExportGrid"的网格。所以$grid.bind("jqGridResizeStop", ...)不起作用。您应该使用正确的ID，并且应该修复调整大小的问题。
