Current behavior
The Typescript definition of sortFunction in Column.d.ts does not match the description in the documentation. https://www.primefaces.org/primereact/#/datatable This causes Typescript errors when defining the sort function.
The Typescript definition is: sortFunction?(): void;

Expected behavior
The Typescript definition should be: sortFunction?({field:string, order:number}): any[];
