默认情况下，集算表将通过一个对象来配置远程请求。如果你想自己处理这些请求，只需将对象替换到函数中。而数据的变化将被传递给函数。
数据变化的细节在 "概览 "的 "请求和响应 "部分。
自动同步模式
在 "自动同步 "模式下处理请求。
批量模式
以 "批处理 "模式处理请求。
改变数据源选项
当一个表使用CRUD函数而不是CRUD选项时，由于安全问题，这些函数在JSON序列化/反序列化后不能被保存和恢复。
在调用fromJSON方法后设置表的数据源选项可以使表重新工作。
重新加载数据
当一个表的fetch方法被调用且其reload参数为真时，该表将再次加载数据。
视图的获取方法与表的获取方法有相同的重载参数。
