Eg, function mapStateToProps(state: MyState) { return { counter: state.counter }; } Here, the prop counter can be inferred to be the same type as state.counter . But

I also know using hashHistory in

问题 I am trying to make a table with antd that allows sorting and row selection (using checkboxes). Right now I have both enabled, however, when I sort by ascending/descending order, the selection does not sort. The checked boxes just stay at the same index as before.
