Temporary table with two tables data with no column in common should return data in one column

Question

I have following temporary table

Create table #Test
(
colA int,
colB int,
colC int,
colD int,
colE int
)

I insert the data in it as follows:

INSERT INTO #Test(colA, colB, colC)
Select A, B C
FROM Table a innerjoin Table b
WHERE (some logic)

INSERT INTO #Test (colD, colE)
Select D, E
FROM Table C innerjoin Table D
WHERE (some logic)

Select * from #Test
drop table #Test

I will get output as :

colA colB colC colD colE
val1 val2 val3 null null
null null null val4 val5

But I need output as follows :

colA colB colC colD colE
val1 val2 val3 val4 val5

Please help me to achieve it.
