Help How to validate these fields in Reactjs

I have tried several functions to achieve validate these within a ReactTable. The Airplane field I want to only allow a maximum of 5 characters, and the Weight field I want to be only numeric. I do not know how

                <ReactTable 
                    contentEditable
                    collapseOnDataChange={false}
                    data={data}
                    itemsPerPage={20}
                    onKeyPress={this.handleKeyPress}
                    columns={[
                        {
                            Header: "Aeronave",
                            columns: [
                                {
                                    Header: "Aeronave",
                                    id: "aeronave",
                                    accessor: flight => ({
                                        arrival: flight.arrival.configuration.aeronave,
                                        departure: flight.departure.configuration.aeronave
                                    }),
                                    width: 50,
                                    className: "center",
