json - 从对象数组创建 PrimeNG TreeTable

Question

我想创建一个树表。名字和姓氏重复的行将被视为子节点。

testData =[ 

{firstName:"Gatorade 600mL 2 for $6.50", lastName:"Doe", age:5000, eyeColor:"blue"}, 

{firstName:"Gatorade 600mL 2 for $6.50 ", lastName:"Doe", age:5000, eyeColor:"blue"}, 

{firstName:"Gatorade 600mL 2 for $6.50 ", lastName:"Doe", age:5000, eyeColor:"blue"}, 

{firstName:"Sunblest 650g to 700g $6.95 ", lastName:"Doe", age:5000, eyeColor:"blue"}, 

{firstName:"Sunblest 650g to 700g $6.95 ", lastName:"Doe", age:5000, eyeColor:"blue"}, 

{firstName:"Sunblest 650g to 700g $6.95 ", lastName:"Doe", age:5000, eyeColor:"blue"}, 

{firstName:"Sunblest 650g to 700g $6.95 ", lastName:"Doe", age:5000, eyeColor:"blue"},
