Mark column as required / Add css class to column header only

[jeff_b]

I have a requirement where a grid will 10 columns with only column 1 and 5 required.   We are looking for a way to make it clear that the columns are required.  I have added stars to the title but I am not sure I like the appearance of that.  Is there a way to color the title font / add a class to JUST the header.  (I tried the cls tag in column model but it appears that only gets applied to the rows).

Basically: Is it possible to mark only required headers in a certain manner?

Title font can be changed with inline css.

Code: [Select]

title: "<span style='color:red;'>Rank</span>"
