DataTable in Lightning component

Hi Team,

I implemented a DataTable in lightning component with lightning:datatable tag.I need to check only one check box at a time and when i checked that check box i need to get that record id into URL.i have one image above the my datatable. When click on that image it should navigate to another compoent with the checked RecordId.
                                     Please help me on this... Thanks in advance
