实际开发场景中，后台返回的数据不一定满足功能需求，这时候就需要根据条件将数据重新组装 ：
GetPermissionList() {
this.loading = true
this.$axios({
method: "post",
url: this.postUrl.GetProjectListUrl,
data: this.$qs.stringify({
isGlobal:this.formselect.IsGlobal
})
})
.then(res => {
this.formselect.totals = res.data.Total
let tableData = [];
let tableChildrenData = [];
res.data.Data.forEach((it, inx) => {
if (it.ParentId == 0) {
tableData.push(it)
} else {
tableChildrenData.push(it)
}
});
tableData.forEach((it0, inx0) => {
it0.Children = [];
tableChildrenData.forEach((it1, inx1) => {
if (it1.ParentId == it0.ID) {
it0.Children.push(it1)
}
});
});
this.tableData = tableData;
this.loading = false
})
.catch(res => {
})
}
