例如:
数组A ={['1001','A'],['1002','B'],['1003','C']}
数组B ={['1001','A','01'],['1002','B','02'],['1003','C','03'],['1001','A','04']}
想得到的结果是:
数组C={['1001','A','01,04'],['1002','B','02'],['1002','B','03']}
例如:
数组A ={['1001','A'],['1002','B'],['1003','C']}
数组B ={['1001','A','01'],['1002','B','02'],['1003','C','03'],['1001','A','04']}
想得到的结果是:
数组C={['1001','A','01,04'],['1002','B','02'],['1002','B','03']}
