在EXTJS Grid中对混合类型的网格列进行排序答案

【问题标题】：Sort Grid Columns of mixed type in EXTJS Grid在EXTJS Grid中对混合类型的网格列进行排序

【问题描述】：

我想对 extjs 列进行排序，列类型为 float，来自服务器我得到的值可以包含“-”值，现在网格会发生什么正在向我显示 NaN 值而不是 - 并且排序不再起作用。

我的要求是创建一个自定义排序，它可以首先根据数字和然后根据字符串排序。

感谢建议渲染器也不适合我。

我的 Json 字符串是：

【解决方案1】：

根据您选择的 Store 创建自定义 Store/对其进行扩展，并覆盖 sortData 方法以创建和使用适当的自定义排序函数（请参阅同一对象中的 createSortFunction 以获取参考 http://dev.sencha.com/deploy/dev/docs/source/Store.html#method-Ext.data.Store-sort）。
