比如數據為a = [{name:"123",age: 12},{name:"222",age: 123},{name:"333",age: 123},{name:"444",age: 123},]b = [{name:"123",age: 12},{name:"222",age: 123},{name:"333",age: 123},{name:"444",age: 123},]同樣的表頭就是：名稱 | 年紀那先把兩個數據加上表頭，然后合并a.unshift({ name:"名稱", age: “年紀”})b.unshift({ name:"名稱", age: “年紀”})res = a.concat(b)export(res)
