New line in Grid header

Dear support,

I am puppulating the hrader of a grid like below:
header+= ‘’ + nlabe + ‘’;

I like to add second line in de header. For example “Customer number” become “Customer [break line] number”.
I have tryed “Customer” + “\n” + “number” but it did not work.

Is this possible in that form of adding header?

Thanks in advanced.

Try to use
instead of “\n”. Also, you have to include column label into CDATA. … er_extra&s[]=complex&s[]=header
