我读取sourceWorkbook获取到sourceCell，然后新创建的destWorkbook创建的destCell,其中复制sourceCell的cellvalue公式值报错：
destCell.setCellFormula(sourceCell.getCellFormula());
其他公式都是没有问题的，但是读取到如下公式的时候会报错：
这是其中报错的公式（我只摘取了两个出来）：
1：
IFERROR(VLOOKUP(E179,[1]详细考勤!$C$3:$Z$4013,8,FALSE),"")
2：
IFERROR(IF(VLOOKUP(E121&$DH$1,[1系统!$A$1:$Z$65536,17,FALSE)="true","√",""),"")
Exception:
java.lang.RuntimeException: not implemented yet
