Merge column over other existing columns

[Polite123]

Hi Experts,

Need some help in merging data.

Input data:

A	B	C
0	1	2

Output data:(I want column D to be over other columns A,B and c in the merged form and should be centre aligned...the image below is incorrect...as D should not be only over A but also B and C...just like D getting merged over A B and C in Excel(Merge and Center))

D
A	B	C
0	1	2

Thanks in advance:)

Thanks in advance

Hi @Polite123 , I was able to add borders to the data except the headers.

Thanks.
