写入
final OutputStream out = new FileOutputStream("out.xlsx");
final SpreadsheetWriter writer = Spreadsheet.getWriterFactory("xlsx").create(out);
try {
writer.configure("encoding", "UTF-8")
.start()
.write("SKU编码", "商品名称", "UPC编码", "价格").next()
.write("B10-4").write("B10-4").write("B10-4").write(35.4);
} finally {

}
按照事件解析
