如何在ArrayFormula中使用COUNTUNIQUE函数并获得范围结果？

您可以这样做：

=ARRAYFORMULA(QUERY(UNIQUE(TRIM(SPLIT(TRANSPOSE(SPLIT(QUERY(TRANSPOSE(QUERY(TRANSPOSE(
 IF(D2:K<>"", "♦"&ROW(A2:A)&"♥"&D2:K, )),,999^99)),,999^99), "♦")), "♥"))),
 "select count(Col1) where Col1 is not null group by Col1 label count(Col1)''", 0))

或像这样：

=ARRAYFORMULA({
 COUNTUNIQUE(D2:H2);
 COUNTUNIQUE(D3:H3); 
 COUNTUNIQUE(D4:H4);
 COUNTUNIQUE(D5:H5);
 COUNTUNIQUE(D6:H6);
 COUNTUNIQUE(D7:H7)})
