Expand functionality (row grouping ) is not working as expected as given in example

below props are passing to table component still in DOM there is no change

expandColumnKey={expandColumnKey}
onRowExpand={onRowExpand}
onExpandedRowsChange={onExpandedRowsChange}
expandIcon={+}
expandedRowRender={row =>

{row.code}

Start by reproducing the example with the listed table props: expandColumnKey, onRowExpand, onExpandedRowsChange, expandIcon, and expandedRowRender. Inspect the table component's row-grouping and expansion entry points to determine why these props produce no DOM change; done means the example expands rows and renders the expected row content.
