如何将过滤器公式创建为数组公式

Question

我有多个依赖于这个公式的列。

我有一个例子，一个员工可以为同一个项目分配多个任务，我使用公式来合并行并添加导致相应行中额外行的值：

我首先执行= Unique(A3:D) 来提取列表，然后：

=IF($A3<>"",join(", ",filter(Sheet1!E$3:E,Sheet1!$A$3:$A=$G3)),"")

我怎样才能使它成为一个 ArrayFormula？ 我是这样尝试的，但结果不正确：

=arrayformula(IF($A2:A<>"",join(", ",filter(Sheet1!E$2:E,Sheet1!$A$2:$A=$G2:G)),""))

一口气搞定：

=ARRAYFORMULA(SPLIT(REGEXREPLACE(SUBSTITUTE(TRIM(TRANSPOSE(QUERY(TRANSPOSE({
 QUERY(QUERY(IF(A3:A<>"", {A3:A&"♦"&B3:B&"♦"&C3:C&"♦"&D3:D, E3:E}, ), 
 "select Col1,count(Col1) where Col1 is not null group by Col1 pivot Col2", 0),
 "select Col1 offset 1", 0),
 IF(QUERY(QUERY(IF(A3:A<>"", {A3:A&"♦"&B3:B&"♦"&C3:C&"♦"&D3:D, E3:E}, ), 
 "select count(Col1) where Col1 is not null group by Col1 pivot Col2", 0), "offset 1",0)<>"", 
 QUERY(QUERY(IF(A3:A<>"", {A3:A&"♦"&B3:B&"♦"&C3:C&"♦"&D3:D, "♦"&E3:E&","}, ), 
 "select count(Col1) where Col1 is not null group by Col1 pivot Col2", 0), "limit 0",1), )})
 ,,999^99))), ", ♦", ", "), ",$", ), "♦"))

仅列K：

=QUERY(ARRAYFORMULA(SPLIT(REGEXREPLACE(SUBSTITUTE(TRIM(TRANSPOSE(QUERY(TRANSPOSE({
 QUERY(QUERY(IF(A3:A<>"", {A3:A&"♦"&B3:B&"♦"&C3:C&"♦"&D3:D, E3:E}, ), 
 "select Col1,count(Col1) where Col1 is not null group by Col1 pivot Col2", 0),
 "select Col1 offset 1", 0),
 IF(QUERY(QUERY(IF(A3:A<>"", {A3:A&"♦"&B3:B&"♦"&C3:C&"♦"&D3:D, E3:E}, ), 
 "select count(Col1) where Col1 is not null group by Col1 pivot Col2", 0), "offset 1",0)<>"", 
 QUERY(QUERY(IF(A3:A<>"", {A3:A&"♦"&B3:B&"♦"&C3:C&"♦"&D3:D, "♦"&E3:E&","}, ), 
 "select count(Col1) where Col1 is not null group by Col1 pivot Col2", 0), "limit 0",1), )})
 ,,999^99))), ", ♦", ", "), ",$", ), "♦")), "select Col5", 0)
