Customize Table Header

For a project I evaluate the ActiveWidgets grid lib.

It is possible to change much of the appereance, but I don't know how to change the header line.

How can i change the background color?

Thank's in advance!

Try a CSS style -
.aw-grid-header {color: blue}
  That actually changes the text colour though. I have never tried to change the backgroud colour but
.aw-grid-header {background:wheat}
  should work.
