How to change a color of single cell in spark DataGrid

Question

假设我有rowIndex和columnIndex，我想改变这个单元格的背景颜色

Answer 1

One way to do it is by extending the default itemRenderer and overriding the set data method:

 override public function set data(value:Object):void {
            super.data = value;
            // retrieve the value of the list-based control's new public property
            var minAge:Number = (listData.owner as MyList).minAge;
            if (data.age < minAge) {
                listLabel.setStyle("color",0xFF0000);
            } else {
                listLabel.setStyle("color",0x000000);
            }
        }
