vue读取本地的excel文件并显示在网页上方法示例

const XLSX = require('xlsx')//将行,列转换function transformSheets(sheets) { var content = [] var content1 = [] var tmplist = [] for (let key in sheets){  //读出来的workbook数据很难读,转换为json格式,参考https://github.com/SheetJS/js-xlsx#utility-functions  tmplist.push(XLSX.utils.sheet_to_json(sheets[key]).length)  content1.push(XLSX.utils.sheet_to_json(sheets[key])) } var maxLength = Math.max.apply(Math, tmplist) //进行行列转换 for (let y in [...Array(maxLength)]){  content.push([])  for (let x in [...Array(tmplist.length)]) {   try {    for (let z in content1[x][y]){     content[y].push(content1[x][y][z])    }   } catch (error) {    content[y].push(' ')   }  } } content.unshift([]) for (let key in sheets){  content[0].push(key) } return content}export {transformSheets as default}
