我初始化几个,就显示几个,我现在就初始化一堆对象。始终不知道为什么
![image image](https://cdn.ostack.cn/v-5feb05cf/global/img/squares.svg)
为什么图片里面数组的内容相同,但是第一个无法被el-table识别,
这两个数组对象的区别在哪,
谢谢大佬帮帮忙
el-table不能正常用
![image image](https://cdn.ostack.cn/v-5feb05cf/global/img/squares.svg)
如图所示,我的数据一共有五条
![image image](https://cdn.ostack.cn/v-5feb05cf/global/img/squares.svg)
但是现在只能显示三条
后端返回的数据如下
{
"history": [
{
"id": "26",
"questionMaster": 1,
"correctedNum": 0,
"disCorrectedNum": 20
},
{
"id": "27",
"questionMaster": 1,
"correctedNum": 0,
"disCorrectedNum": 20
},
{
"id": "28",
"questionMaster": 1,
"correctedNum": 0,
"disCorrectedNum": 20
},
{
"id": "29",
"questionMaster": 1,
"correctedNum": 0,
"disCorrectedNum": 20
},
{
"id": "30",
"questionMaster": 1,
"correctedNum": 0,
"disCorrectedNum": 20
}
]
}
