Set cellType in header row

Hi,
is it possible to set the cellType only for header cells? I need to have header cell in form “img + value”. I know, i can have it with “custom_excell”, but how can i use it in header?

Thanks in advance,

It not possible to set cellType for grid header. Cell types work only for grid rows. As work around you can insert complex html into grid header cell:
grid.setHeader(“Text…”);
