      ]

exportArrayDataToExcel() {
     const wb = XLSX.utils.book_new(); // 创建工作簿
     const ws = XLSX.utils.aoa_to_sheet(this.exportArrayData); //  创建工作表
     const cols = [];
	// 设置列宽
     for (let i = 0; i < this.exportArrayData[0].length; i++) {
       cols.push({ wch: 15 });
     }
     ws['!cols'] = cols;
     XLSX.utils.book_append_sheet(wb, ws, 'exportArrayDataToExcel');
     // 导出Excel
     XLSX.writeFile(wb, '表格.xlsx');
   },
