POI操作Excel中,导出的数据不是很大时,则不会有问题,而数据很多或者比较多时,
就会报以下的错误,是由于cell styles太多create造成,故一般可以把cellstyle设置放到循环外面
报错如下:
Caused by: java.lang.IllegalStateException: The maximum number of cell styles was exceeded. You can define up to 4000 styles in a .xls workbook

方法二(不推荐,影响性能):
1.4000最大样式错误
java.lang.IllegalStateException: The maximum number of cell styles was exceeded. You can define up to 4000 styles in a .xls workbook错误
找到zpoi.jar中org.zkoss.poi.hssf.usermodel.HSSFWorkbook修改createCellStyle函数内的最大样式数量即可。重新打zpoi.jar即可。
IE兼容问题
数字形式写入代码
写入日期代码
