魔方网表中如何把数字日期格式转中文日期格式
例如把2012-05-31转换为二○一二年五月三十一日
公式如下：
CHOOSE(MID(TEXT($MF(日期)$,"yyyy"),1,1)+1,"○","一","二","三","四","五","六","七","八","九")&CHOOSE(MID(TEXT($MF(日期)$,"yyyy"),2,1)+1,"○","一","二","三","四","五","六","七","八","九")&CHOOSE(MID(TEXT($MF(日期)$,"yyyy"),3,1)+1,"○","一","二","三","四","五","六","七","八","九")&CHOOSE(MID(TEXT($MF(日期)$,"yyyy"),4,1)+1,"○","一","二","三","四","五","六","七","八","九")&"年"&CHOOSE(TEXT($MF(日期)$,"MM")+0,"一","二","三","四","五","六","七","八","九","十","十一","十二")&"月"&IF(TEXT($MF(日期)$,"dd")+0 < 16,CHOOSE(TEXT($MF(日期)$,"dd")+0,"一","二","三","四","五","六","七","八","九","十","十一","十二","十三","十四","十五"),CHOOSE(TEXT($MF(日期)$,"dd")-15,"十六","十七","十八","十九","二十","二十一","二十二","二十三","二十四","二十五","二十六","二十七","二十八","二十九","三十","三十一"))&"日"

$MF(日期)$指数字日期字段 可以在一个文本字段中启用上述公式存储转换后的中文日期
