CSS styling of custom cells in the multiline header

Hello,

I have a multiline header and I would like to add a css class to a selected header cell. How can I do that? I saw that it is possible for all elements in the header column but I would like to add my css only to selected ones.

Hi dex,

You can add CSS to any header cell no matter how many cells there are in the header array:

{ id:"title", header:[ 
       {text:"One", css:'some_class'}, 
       {text:"Two", css:{"background-color":"yellow"}}
]}
