vue中导出excel表格， Workbook 导出的表格的单元格格式设置为文本

<template>
  <button @click="exportExcel">导出Excel</button>
</template>
 
<script>
import XLSX from 'xlsx';
 
export default {
  methods: {
    exportExcel() {
      // 创建Workbook和工作表
      const workbook = XLSX.utils.book_new();
      const worksheet = XLSX.utils.aoa_to_sheet([
        ['姓名', '年龄', '邮箱'],
        ['Alice', 28, '[email protected]'],
        ['Bob', 22, '[email protected]']
      ]);
       // 设置姓名列的文本格式
      const nameCellRef = XLSX.utils.encode_cell({ c: 0, r: 0 }); // 第一行第一列
      worksheet[nameCellRef].z = 'm'; // 设置单元格格式为文本
      worksheet[nameCellRef].z = '@'; // 设置单元格格式为文本，数字也是按照字符串处理 

      // 将工作表添加到Workbook
      XLSX.utils.book_append_sheet(workbook, worksheet, 'Sheet1');
       // 生成Excel的配置
      const wbout = XLSX.write(workbook, { bookType: 'xlsx', type: 'binary' });
 
      // 创建二进制对象并创建url
      const blob = new Blob([s2ab(wbout)], { type: 'application/octet-stream' });
      const url = URL.createObjectURL(blob);
 
      // 创建a标签模拟点击进行下载
      const a = document.createElement('a');
      if (typeof a.download === 'undefined') {
        window.location = url;
      } else {
        a.href = url;
        a.download = 'formatted_excel.xlsx';
        document.body.appendChild(a);
        a.click();
        document.body.removeChild(a);
      }
 
      // 清除对象URL
      setTimeout(function() { URL.revokeObjectURL(url); }, 100);
    }
  }
};
 
// 将字符串转换为ArrayBuffer
function s2ab(s) {
  const buf = new ArrayBuffer(s.length);
  const view = new Uint8Array(buf);
  for (let i = 0; i !== s.length; ++i) view[i] = s.charCodeAt(i) & 0xFF;
  return buf;
}
</script>

是在具体的列为文本格式

//设置第colum列为文本格式，输入的内容按照字符串显示
function sheet_from_array_of_arrays_column(data, column) {
    var ws = {};
    var range = {s: {c: 100000, r: 100000}, e: {c: 0, r: 0}};
    for (var R = 0; R != data.length; ++R) {
        for (var C = 0; C != data[R].length; ++C) {
           
               
            if (range.s.r > R) range.s.r = R;
            if (range.s.c > C) range.s.c = C;
            if (range.e.r < R) range.e.r = R;
            if (range.e.c < C) range.e.c = C;
            var cell = {v: data[R][C]};
            if (C==column) {
                cell.z = '@';
                }
           if (C==column && cell.v == null){
            cell.v ='';
           }
            var cell_ref = XLSX.utils.encode_cell({c: C, r: R});
            if (typeof cell.v === 'number') cell.t = 'n';
            else if (typeof cell.v === 'boolean') cell.t = 'b';
            else if (cell.v instanceof Date) {
                cell.t = 'n';
                cell.z = XLSX.SSF._table[14];
                cell.v = datenum(cell.v);
            }
            else cell.t = 's';
 
            ws[cell_ref] = cell;
        }
    }

    if (range.s.c < 10000000) ws['!ref'] = XLSX.utils.encode_range(range);
    return ws;
}

生成表格

export function export_json_to_excel_column(th, jsonData, defaultTitle,column) {
    /* original data */
    var data = jsonData;
    /*方法可向数组的开头添加一个或更多元素，并返回新的长度。*/
    data.unshift(th);
    var ws_name = "SheetJS";
    var wb = new Workbook(), ws = sheet_from_array_of_arrays_column(data,column);   
   //   const nameCellRef = XLSX.utils.encode_cell({ c: 1, r: 0 }); // 第一行第一列
    //  console.log(nameCellRef);
     // ws[nameCellRef].z = '@'; // 设置单元格格式为文本
    /* add worksheet to workbook */
    wb.SheetNames.push(ws_name);
    wb.Sheets[ws_name] = ws;
    var wbout = XLSX.write(wb, {bookType: 'xlsx', bookSST: false, type: 'binary'});
    var title = defaultTitle || '列表'
    saveAs(new Blob([s2ab(wbout)], {type: "application/octet-stream"}), title + ".xlsx")
}
