添加更多 65 列时数据表出错？
datatable giving error when adding more 65 columns?
我在我的 mvc asp.net 应用程序中使用数据table，当我使用 65 列时它工作得很好但是当我再添加一列时它给我错误，即 DataTables 警告：table id=userTrackingList_table - Ajax 错误。有关此错误的更多信息，请参阅 http://datatables.net/tn/7. 在控制台上，错误消息是：无法加载资源：服务器响应状态为 400（错误请求）。

如您所见，我添加了 65 列，因为我在此处再添加 1 列，它会出错。我已经检查过我的后端完全没问题，只有当列数增加时才会抛出上述错误。
我在 ajax 部分犯了错误，添加 "type" : "POST" 代码会 运行 正常.
由于 ajax 请求的 "type" 默认未定义 "GET" 请求正在运行，但 get 请求被服务器拒绝.
