主题：请老师帮我写个数合并的公式好吗？

if(Instr("0",[数据一]+[数据二])>-1,"0","")+if(Instr("1",[数据一]+[数据二])>-1,"1","")+if(Instr("2",[数据一]+[数据二])>-1,"2","")+if(Instr("3",[数据一]+[数据二])>-1,"3","")+if(Instr("4",[数据一]+[数据二])>-1,"4","")+if(Instr("5",[数据一]+[数据二])>-1,"5","")+if(Instr("6",[数据一]+[数据二])>-1,"6","")+if(Instr("7",[数据一]+[数据二])>-1,"7","")+if(Instr("8",[数据一]+[数据二])>-1,"8","")+if(Instr("9",[数据一]+[数据二])>-1,"9","")

如果用eval能简化很多,不过没什么必要
