//docx文档预览组件
npm install @vue-office/docx vue-demi
 
//excel文档预览组件
npm install @vue-office/excel vue-demi
 
//pdf文档预览组件
npm install @vue-office/pdf vue-demi

// docx文档引入、注册
import VueOfficeDocx from '@vue-office/docx'

export default {
  components: { VueOfficeDocx }
}

 
 
// excel文档引入、注册
import VueOfficeExcel from '@vue-office/excel'
import '@vue-office/excel/lib/index.css'
 

export default {
  components: { VueOfficeDocx }
}

 
// pdf文档引入、注册
import VueOfficePdf from '@vue-office/pdf'
 

export default {
  components: { VueOfficeDocx }
}
