因此，我使用JQGrid生成表。数据从数据库中读取，表格通过JSON填充。一旦表格被渲染，所有的排序和编辑都在本地完成，直到数据被保存到数据库中。我正在使用sortableRows函数，以便我可以拖放和重新排序行;它正在按预期工作，除了我还希望根据新订单来更改特定列的值。我一直在关注这个例子here，正如我正在做的那样，但是看着源代码并没有给我带来太多的好处。我相信它与update()函数有关。JQGrid sortableRows更改排序列值以匹配新订单
我希望显示顺序列的值从0开始重新编号，依次取决于行的新顺序。就像在我的例子
任何人都可以给我一些正确的方向的见解吗？
这里是我的jqGrid代码：
