Conditional format - compare two cells

Question:
Is there a way two compare two cells and highlight the cell which is bigger?

Solution:
See the javascript used in demo http://phpgrid.com/example/row-level-permission-edit-condtion/. When condition is met, can do something like the following in the Javascript.

jQuery("#TABLENAME").jqGrid("setCell", row, col, value,{background:'#ff0000'});

Complete code:

<?php
// note this should not replace database role-based or user-based permissions.
$onGridLoadComplete = <<<ONGRIDLOADCOMPLETE
function(status, rowid)
{
    var ids = jQuery("#orders").jqGrid('getDataIDs');
    for (var i = 0; i < ids.length; i++)
    {
        var rowId = ids[i];
        var rowData = jQuery('#orders').jqGrid ('getRowData', rowId);

        var requiredDate = new Date($("#orders").jqGrid("getCell", rowId, "requiredDate"));
        var shippedDate = new Date($("#orders").jqGrid("getCell", rowId, "shippedDate"));

        // compare two dates and set custom display in another field "status"
        if(requiredDate < shippedDate){
           
            $("#orders").jqGrid("setCell", rowId, "status", '', {'background-color':'gold'});
               
        }
    }

}
ONGRIDLOADCOMPLETE;


$dg = new C_DataGrid("SELECT * FROM orders", "orderNumber", "orders");
$dg->set_col_hidden('comments');
$dg->add_event("jqGridLoadComplete", $onGridLoadComplete);
$dg->enable_edit('INLINE', 'CRUD');

$dg -> display();
?>
