TS2339: Property does not exist on type {} when extending a class (of Antd)

I am quite new to Typescript, but I have to debug somebody else’s code. It is about a component in componentsViewTable.tsx which worked previously, before updating TS/JS packages. It contains the following code

 Lines 8-9
import { Table } from "antd";
const { Column, ColumnGroup } = Table;
 Line 52
class MyTable extends Table<Interfaces.ViewEntry>;
 ...
export class ViewTable extends React.Component<ViewTableProps, ViewTableState> {
   render() {
        return (
            <div>
                <div className="view-table">
 Line 97ff
                    <MyTable size="small" dataSource={this.props.viewData}
                        rowKey={(record) => (record.GeneralLedgerId).toString()}
                        locale={{ emptyText: 'No applicable view data found' }}
                        pagination={false}>
 ... 

This used to work, but after an update to the most recent versions of React(-Dom) (both version 16.10.2), Antd (version 3.24.0), Typescript (version 3.6.4), I get errors galore:

Error TS2459 (TS) Type ‘ComponentClass, “loading” | “footer” | “style” | “title” | “scroll” | “size” | “children” | “className” | “prefixCls” | “locale” | “getPopupContainer” | “onChange” | “dataSource” | … 27 more … | “sortDirections”>, any>’ has no property ‘ColumnGroup’ and no string index signature. 9

Reading documentation and searching on the web with different search terms did not help. May you be so kind and give me a hint what is happening?
