返回排除其他列表的唯一列表

Question

我想返回一组唯一值，其中包含跨多个列的分类变量，这些变量排除了另一个列表中的值。

=UNIQUE(QUERY({J2:J,K2:K},"select * where Col1 is not null"))

这适当地返回带有分类变量的唯一值集，但我似乎无法弄清楚如何从另一个列表中排除值。

=UNIQUE(FILTER(J2:K,ISNA(MATCH(M2:N,J2:K,0))))

我尝试过使用它，但它会返回

#VALUE! FILTER range must be a single row or a single column.

任何帮助，将不胜感激！

Answer 1

=ARRAYFORMULA(IFERROR(SPLIT(FILTER(
 TRANSPOSE(QUERY(TRANSPOSE(UNIQUE(A2:B)), , 999^99)), NOT(COUNTIF(
 TRANSPOSE(QUERY(TRANSPOSE(       D2:E) , , 999^99)), 
 TRANSPOSE(QUERY(TRANSPOSE(UNIQUE(A2:B)), , 999^99))))), " ")))

考虑带空格的物品：

=ARRAYFORMULA(SUBSTITUTE(IFERROR(SPLIT(FILTER(
 TRANSPOSE(QUERY(TRANSPOSE(UNIQUE(SUBSTITUTE(A2:B," ","♦"))),,999^99)), NOT(COUNTIF(
 TRANSPOSE(QUERY(TRANSPOSE(       SUBSTITUTE(D2:E," ","♦")) ,,999^99)), 
 TRANSPOSE(QUERY(TRANSPOSE(UNIQUE(SUBSTITUTE(A2:B," ","♦"))),,999^99)))))," ")),"♦"," "))
