The jqgrid cells contains tooltip showing the full content of the cells. It would be nice if the header cells could also contain tooltip showing the full content of the cells.
I guess you can can get the IDs of the header cells (you can use FireBug to see which IDs jqGrid assigns to headers) and with jQuery you can set the “title” attribute of the cells – this will essentially provide the tooltips. This can be done in window.load or document.ready events.
