DataGrid Column HeaderText Multiline?

I m trying to create a datagrid on flash cs3 with AS3. I have managed to make the cells multiline and wordwrap. But I couldnt make the headers of the columns multiline and wordwrap. Please help me.

[FONT=“Arial Black”]Here is my .as file code:[/FONT]

package {

	    import fl.controls.listClasses.CellRenderer;
         
        public function MultiLineCell()
        {    
            textField.wordWrap = true;
            textField.autoSize = "left";
        }
        override protected function drawLayout():void {             
            textField.width = this.width;
            super.drawLayout();
        }
    }
}

[FONT=“Arial Black”]Here is my AS3 code in my main .fla file[/FONT]

import fl.data.DataProvider; 
import fl.controls.dataGridClasses.DataGridColumn; 
 
aDg.rowHeight=50; 
 
 
var model_v:DataGridColumn = new DataGridColumn("model");
var maksyuk_v:DataGridColumn = new DataGridColumn("maksyuk");

model_v.headerText = "Model";
model_v.cellRenderer=MultiLineCell;

maksyuk_v.headerText = "Maks Yuk c:222   f*2";
maksyuk_v.width = 100;
maksyuk_v.cellRenderer=MultiLineCell;

aDg.addColumn(model_v);
aDg.addColumn(maksyuk_v);

 
aDg.addItem({model:"GZ5",maksyuk:"5000      3000      900000     9690000"});
