只能选择同一实例名下的多个数据库 第一级单选，其他禁用 缺点：table每一行dboptions不一样（disabled不同）
<el-cascader expand-trigger="hover"
:options="scope.row.dboptions"
:props="{ multiple: true }"
v-model="scope.row.db"
filterable
clearable
style="width:100%;"
@change="changedboptions(scope.row)">
</el-cascader> changedboptions(row){
if (row.db.length !== 0) {
for (var i = 0; i < row.dboptions.length; i++) {
if (row.dboptions[i].value !== row.db[0][0]) {
row.dboptions[i].disabled = true
}
}
} else{
for (var i = 0; i < row.dboptions.length; i++) {
row.dboptions[i].disabled = false
}
}
},
同一实例下的自动全选 
<el-cascader expand-trigger="hover"
:options="dboptions"
:props="{ multiple: true }"
v-model="scope.row.db"
filterable
clearable
style="width:100%;"
@change="changemongodb(scope.row)">
</el-cascader> changemongodb(row){
if (row.db.length !== 0) {
// 找到第一级，可多个
var firstarray = []
for (var i = 0; i < row.db.length; i++) {
if (firstarray.indexOf(row.db[i][0]) == -1) {
firstarray.push(row.db[i][0])
}
}
// 全选第二级
row.db = []
for (var i = 0; i < this.dboptions.length; i++) {
if (firstarray.indexOf(this.dboptions[i].label) !== -1) {
for (var j = 0; j < this.dboptions[i].children.length; j++) {
var array = []
array[0] = this.dboptions[i].label
array[1] = this.dboptions[i].children[j].label
row.db.push(array)
}
}
}
}
}, 一个实例全选
在上一个基础上，一级单选 <el-cascader expand-trigger="hover"
:options="dboptions"
:props="{ multiple: true }"
v-model="scope.row.db"
filterable
clearable
style="width:100%;"
@change="changemysql(scope.row)">
</el-cascader> changemysql(row){
if (row.db.length !== 0) {
// 只要一个集群，选择最新选择的集群
if (row.name && row.db[0][0] === row.name) {
row.name = row.db[row.db.length-1][0]
} else{
row.name = row.db[0][0]
}
// 全选第二级
row.db = []
for (var i = 0; i < this.dboptions.length; i++) {
if (this.dboptions[i].label === row.name){
for (var j = 0; j < this.dboptions[i].children.length; j++) {
var array = []
array[0] = this.dboptions[i].label
array[1] = this.dboptions[i].children[j].label
row.db.push(array)
}
}
}
}
},
