vue导出excel表格，自定义字体样式，字体颜色，合并单元格，单元格填充色-xlsx以及xlsx-style，JSZip为2.XX版本

先装包

安装注意

import XLSX from "xlsx-style"报错：This relative module was not found: ./cptable in ./node_modules/xlsx-style@0.8.13@xlsx-style/dist/cpexcel.js

需要修改源码：
在\node_modules\xlsx-style\dist\cpexcel.js 807行的 var cpt = require(’./cpt’ + ‘able’); 改成 var cpt = cptable;
xlsx-style的样式源码文档，说实话，我看不太懂
参考资料，来自这个位大哥，里面还有发npm包的链接
