本来用的xlsx和xlsx-style两个插件，过程一步一个坑，到完全能用要消灭好多bug。这时发现了exceljs，真香😀

		<script>
			function exporting() {
				// 创建工作簿
				const workbook = new ExcelJS.Workbook()
				// 添加工作表
				const worksheet = workbook.addWorksheet('sheet1')



				// 设置表头
				worksheet.columns = [{
						header: '名次',
						key: 'sort',
						width: 10
					},
					{
						header: '班级',
						key: 'class',
						width: 20
					},
					{
						header: '姓名',
						key: 'name',
						width: 20
					},
					{
						header: '得分',
						key: 'score',
						width: 10
					},
				]

				// 添加表体数据
				worksheet.addRow({
					sort: 1,
					class: '前端三班',
					name: 'Buer',
					score: 99
				})
				worksheet.addRow({
					sort: 2,
					class: '前端一班',
					name: 'Jack',
					score: 86
				})
				worksheet.addRow({
					sort: 3,
					class: '前端一班',
					name: 'Mary',
					score: 58
				})


				// 设置单元格 
				const aCell = worksheet.getCell('A1')
				// 1.边框 https://github.com/exceljs/exceljs/blob/HEAD/README_zh.md#%E8%BE%B9%E6%A1%86
				aCell.border = {
					top: {
						style: 'thin'
					},
					left: {
						style: 'thin'
					},
					bottom: {
						style: 'thin'
					},
					right: {
						style: 'thin'
					},
				}
				// 2.填充 https://github.com/exceljs/exceljs/blob/HEAD/README_zh.md#%E5%A1%AB%E5%85%85
				aCell.fill = {
					type: 'pattern',
					pattern: 'mediumGray',
					fgColor: {
						rgb: '#c2c2c2'
					}
				}

				// 设置行样式 https://github.com/exceljs/exceljs/blob/HEAD/README_zh.md#%E5%AD%97%E4%BD%93
				worksheet.getRow(1).font = {
					bold: true,
				}










				// 导出表格
				workbook.xlsx.writeBuffer().then((buffer) => {
					const blob = new Blob([buffer], {
						type: ''application/vnd.openxmlformats-officedocument.spreadsheetml.sheet''
					})
					const link = document.createElement('a')
					link.href = URL.createObjectURL(blob)
					link.download = '测试' + '.xlsx'
					link.click()
					URL.revokeObjectURL(link.href) // 下载完成释放掉blob对象
				})
