Working with version 7.5.0...
How can I export to excel the 'background-color' set in styleHead on the colModel?
...
{ title: "Source", dataIndx: "Source", styleHead: { 'background-color': '#ffffff' } },
{ title: "Source", dataIndx: "Source", styleHead: { 'background-color':'#007cb0' } },
...
however they export into excel with grey background color (bgColor).
Thank you for your assistance.
