是否有公式可从Google表格中的框中提取特定字符？

Question

我有6列和4行，例如：

-- Here is what I used, and it works:
create table temp_table like my_table;
-- t_id is my unique column
insert into temp_table (id) select id from my_table GROUP by t_id;
delete from my_table where id not in (select id from temp_table);
drop table temp_table;

现在我希望我的最终数据如下：

A B C D E F,  A B C D,  A B C, A B C D E 

我使用了串联公式，但得到的结果如下：

A>B>C>D>E>F,  A>B>C>D,  A>B>C,  A>B>C>D>E 

在此列中没有可用数据时，我不需要A>B>C>D>E>F, A>B>C>D>, A>B>C>>, A>B>C>D>E> 字符 我尝试过

Answer 1

有几种解决方法，例如使用REGEXREPLACE或SUBSTITUTE：

=SUBSTITUTE(A12, ">>", ">")

---

=REGEXREPLACE(A12, ">>", ">")

或IF语句，例如：

=ARRAYFORMULA(IF(A1:F1<>"", A1:F1&">", ))

=JOIN( , ARRAYFORMULA(IF(A1:F1<>"", A1:F1&">", )))

---

或简单的TEXTJOIN

=TEXTJOIN(">", 1, A1:F1)

df1 <- structure(list(Sno = 1:4, number = c("122, apple, 22, banana", 
"145, 20, 45", "212, grapes, 33", "250, sugar, 43")), class = 
"data.frame", row.names = c(NA, -4L))

df2 <- structure(list(Sno = 1:6, number = c(122L, 186L, 212L, 250L, 
111L, 45L)), class = "data.frame", row.names = c(NA, -6L))
