我有一个像上面的googlesheetlink看起来像这样

Timestamp   Exact   Username of Hacker  Video Link
6/30/2020 1:55:21   Column1DummyData    
6/30/2020 1:59:09   Column1DummyData    
6/30/2020 1:59:14   Column1DummyData    
6/30/2020 1:59:19   Column1DummyData

我使用查询设法得到了这样的输出:

=QUERY(B2:B, "select B,count(B) where B is not null group by B label count(B)''")

Name               NumberOfItem 

Column1DummyData         4

Svd                      2

qwerty                   1

test                     3        

但我需要这样的输出

Name               NumberOfItem    Video link

Column1DummyData         4

Svd                      2

qwerty                   1

test                     3         https://www.youtube.com/watch?v=3UZzu4UQLcI, https://www.youtube.com/watch?v=HbgzrKJvDRw, https://www.youtube.com/watch?v=gxpX_mubz2A

尝试:

=ARRAYFORMULA({
 QUERY(B2:B, "select B,count(B) where B !='' group by B label count(B)''"), IFNA(VLOOKUP(
 QUERY(B2:B, "select B,count(B) where B !='' group by B label count(B)''"), {
 QUERY(B2:C, "select B,count(B) where B !='' and C !='' group by B label count(B)''"), 
 REGEXREPLACE(TRIM(TRANSPOSE(QUERY(TRANSPOSE(IF(QUERY(
 QUERY(B2:C, "select count(B) where B !='' and C !='' group by B pivot C"), 
 "offset 1", 0)="",,QUERY(
 QUERY(B2:C, "select count(B) where B !='' and C !='' group by B pivot C"), 
 "limit 0", 1)&",")),,99^99))), ",$", )}, 3, 0))})
