schema has three params ,a,b,c
message a：\{ "a": 1, "b": 1, "c": 2}
message b：\{ "a": 1, "b": null, "c": 2}
message c：\{ "a": 1, "c": 2}
turn message into row , message a is ok, but we cant distinguish message b and
message c if we use null, when deal message c ,we must use like NaN row(2,NaN),
i think row need a easy way to show message b and message c with row
