vue中使用ts时如何导入mixins

// mixins.ts
import { Vue } from "vue-property-decorator";
export class TableSelect extends Vue {
    selected: Array<any> = [];
    tableChange(val: Array<any>) {
        this.selected = val;
    }
}
// pagea.vue
import { Component } from "vue-property-decorator";
import {TableSelect } from 'mixins'
@Component
export default class Hone extends TableSelect {
  // do something   
}
