Add Custom Rows Rows

Hi,

Great work! I was able to successfully use your class. However, I need to add a custom row to the current sheet.

e.g the active sheet contains these data

col1 col2 col3 col4
1 2 3 4
2 7 9 8

I want it so that the display would be like this in one sheet :

col1 col2 col3 col4
1 2 3 4
2 7 9 8

coln1 coln2 coln3 coln4
1 2 3 4
2 7 9 8


Is this possible on the current version ?

Thanks!
