Dear Experts

I have table1, containing data as follows

month pen pencil book
jan 15 20 35
feb 27
feb 37 16
mar 5 7 98
apr 47
apr 46
apr 45


In table1, month feb and apr comes more than one times. If a month comes more than one times then data of other records of the same month should come in first occourance in related fields. I do not want to use command like select sum(pen). The result should look this

month pen pencil book
jan 15 20 35
feb 37 27 16
mar 5 7 98
apr 45 46 47

Please help
