Use the unknown type in typescript 3.0 to improve defintions

• I have searched the issues of this repository and believe that this is not a duplicate.

What problem does this feature solve?

Let's take Table.Column for an example:

export interface ColumnProps<T> {
    // ...
    render?: (text: any, record: T, index: number) => React.ReactNode;
    onFilter?: (value: any, record: T) => boolean;
}

It's very easy to mistake text as record and write down <Column render={item => item.prop}/>

What does the proposed API look like?

Replace any with unknown when it makes sense.
Definition of render should be render?: (text: unknown, record: T, index: number) => React.ReactNode;

Note: unknown is a breaking change to TS 2.x users.

Sounds great, but it shouldn’t be a break change when 3.x is not yet popular.
