I was working on creating nested grid with the ability to expand/collapse rows, so i used rowexpander plugin.
I need a custom header for the column which contains the expander.
For example, on the first grid here: http://docs.sencha.com/ext-js/4-1/#!...d-plugins.html you can see empty header for the first column, I'd like to customize it with my own markup..
So, I found one possible solution (just to overwrite the header on grid beforerender event), but I really don't like it.
Does anybody know how can I customize the header?
