我在上面的谷歌工作表中的 A2 上使用了以下公式

=regexextract(A2,"[\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]*")

但 B2 细胞给出以下错误

Function REGEXEXTRACT parameter 2 value "[\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]* [\w]*" does not match text of Function REGEXEXTRACT parameter 1 value "Immediate Hiring ! !
