合并JOIN和ARRAYFORMULA不起作用

Question

Column B   Column B    Desired output
Some       Thing       Some Thing
Any                    Any (with NO blank space because of blank cell)
No         Thing       No Thing
           Thing       Thing (with no leading space either)

我已经尝试过：={"COPY-PASTE" ; ARRAYFORMULA(TEXTJOIN(" "; SAND; $B$2; $C$2))}-没有成功。

Answer 1

=ARRAYFORMULA(TRIM(TRANSPOSE(QUERY(TRANSPOSE(A1:B),,999^99))))
