It is recommended to give `sfc template` a name prop

[xxbld]

• a super component in jsx

  // BaseCard
  export default {
  methods:{
      renderContent(){
          // implements in sub class 
      }
  },
  render() {
      return (
          <div>
              {/*  header */}
              {this.renderContent()}
              {/* bottom */}
          </div>
      )
  }
  }

• expected implements in sfc

  
  <template name="renderContent">
  <div>
         aaa
  </div>
  </template>
