Using images in header

dhtmlxGrid allows using images for column headers formating. In this case you can specify different images for column header, sorted in ascending and descending way.

Some notes about using images as column headers:

create two additional images for sorting (asc,desc) using original image name as follows:

original: column_a.gif
asc: column_a.asc.gif
desc: column_a.des.gif

Take into account that IE and Mozilla count the width of cell differently (ie: with border, mozilla: without)

Put all (three per column) images in grid images folder.
