Thanks for your reply,

I want a function like my screenshot below:

$("#grid").igGrid({
dataSource: data2,
primaryKey: "ID",
autoCommit : true,
autoGenerateColumns: true,
renderCheckboxes : true,
columns: [
{ key: "ID", headerText: "ID", width: "20px", dataType: "string", columnCssClass: setBackgroudIro1(record, columnsetting) }
],
features:[
{
name: "Updating",
enableAddRow: true,
editMode: "row",
enableDeleteRow: true
}
]
});
function setBackgroudIro1(item, column) {
        if (item.name == null) {
             if ((column.dataType == null) || (column.dataType != "number")) {
                  switch (column.key) {
                              case 'key1': return 'cssclassA';
                              case 'key2': return 'cssclassB';
                   }
             }
        }
}

Can I do it?
