导出Excel时候出现一个问题:
比如是”订单号”、“手机号”、“身份证”等等,他是一个一长串的数字组成的字符串,导出到EXCEL之后office傻不拉几的自以为是的将这串数字字符串转成“科学计数法”,变成如下:
此外，EXCEL还会自动将日期转为英文日期格式，如：
如何解决呢？？
解决的方法一:
导出这个数字字符串的时候,在这串数字前面加一个: 英文的 全角的 单引号 ＇
效果如下:
有了这个单引号’ 之后, EXCEL 就认为这个值是字符串了,就不会当做他是数字了,也就不会科学计数法了!
最后再说一遍：
给你的 一长串 数字的 字符串 前面加上:
英文的 全角的 单引号 ＇
解决的方法二:
或者在每个<td>里添加样式: style=’mso-number-format:\”\@\”;’
<td style='mso-number-format:\"\@\";'>7894561230123456789</td>也能实现这个效果
附上完整 table2excel.js 代码(已添加: style=’mso-number-format:\”\@\”;’ , 见112行 ):
/* 调用方法:
* $('#test_table').table2excel({//'#test_table' table的id
* subtotal: 1,//可选参数(可删除此行),默认值:0
* width:200,//导出excel表格的宽度百分比的值(不含%号),可删除此行(默认100%)
* filename: 'excel_' + new Date().getTime() + '.xls', //excel文件名称,扩展名:.xlsx 或者.xls
* });
