vue中excel导入导出组件
vue中导入导出excel，并根据后台返回类型进行判断，导入到数据库中
功能：实现js导入导出excel，并且对导入的excel进行展示，当excel标题名称和数据库的名称标题匹配时，则对应列导入的数据自动渲染展示在表格中，预览展示10条，不足10条的的用空行表示。可通过下拉框动态切换对应列的值。图片保存到系统中是将有src属性的img值替换为后台传递过来的七牛云地址，导入完成后，部分导入失败的数据可以下载到本地查看
导入的excel文件
使用该导入功能需安装依赖 npm install xlsx
需要使用导入导出功能的自行复制对应方法进行使用
exportData是用于导入的
tableToExcel 和 exportPathMethod是用于导出的
