<el-tree-select
            v-model="form.topmneu"
            :data="tableData"
            :props="{ label: 'title', value: 'id' }"
            :render-after-expand="false"
            style="width: 100%"
            check-strictly
          />

添加 :props = "{ lable : ' 字段名 ' , value: ' 字段id ' }"

完美解决
