150 Views and I think nobody does understand what you are talking about.
What exactly do you want?
Do you want to add a second Headerline to display both languages at the same time?
or
do you just want displayed the right value depending sy-langu?
If the second case is yours then just link your internal table to a dict-structure and use the data-elements where the values came from.
That should fix your problem.
I think you need a tutorial. Here is a discussion with a lot of such content
