TS: 我发现 dataIndex 可以推导出来，但是 目前的ts声明里面没有，请问可以加一下吗?

Before:

export interface ColumnType<RecordType> extends ColumnSharedType<RecordType> {
    colSpan?: number;
    dataIndex?: DataIndex;
    render?: (value: any, record: RecordType, index: number) => React.ReactNode | RenderedCell<RecordType>;
    shouldCellUpdate?: (record: RecordType, prevRecord: RecordType) => boolean;
    rowSpan?: number;
    width?: number | string;
    onCell?: GetComponentProps<RecordType>;
    /** @deprecated Please use `onCell` instead */
    onCellClick?: (record: RecordType, e: React.MouseEvent<HTMLElement>) => void;
}

The suitable I think:

export interface ColumnType<RecordType> extends ColumnSharedType<RecordType> {
    colSpan?: number;
    dataIndex?:  keyof RecordType;
    render?: (value: any, record: RecordType, index: number) => React.ReactNode | RenderedCell<RecordType>;
    shouldCellUpdate?: (record: RecordType, prevRecord: RecordType) => boolean;
    rowSpan?: number;
    width?: number | string;
    onCell?: GetComponentProps<RecordType>;
    /** @deprecated Please use `onCell` instead */
    onCellClick?: (record: RecordType, e: React.MouseEvent<HTMLElement>) => void;
}

Search the repository for the ColumnType and DataIndex declarations, then inspect nearby TypeScript type tests or usage examples. Check whether dataIndex can be constrained to RecordType keys without breaking existing table columns; done means the declaration accepts valid keys and the relevant type checks pass.
