dynamic LabelFunction for daynamically created datagrid column

Iam creating a datagrid column dynamically  like this.
for (ii = 1; ii<=nbOfpps; ii++){
      nwColumn= new DataGridColumn(ii.toString());
                                          nwColumn.dataField = "corr" + ii.toString()
                                          nwColumn.width=50;
                                          nwColumn.labelFunction  
                                          nwColumnsArray.push(newColumn);
}
I want to set the format of this column to 6 decimal places. Can u some one say how? Remember the column name is formed by ii.toString()

or maybe assigning the labelFunction is without "":

nwColumn.labelFunction = formatFunc;

Give this a try:

nwColumn.labelFunction = "formatFunc";

<mx:NumberFormatter id="numberFormatter" precision="6"
        useThousandsSeparator="true" useNegativeSign="true"/>

private function formatFunc( item:Object, column:DataGridColumn):String {
       return numberFormatter.format(item[column.dataField]);
}
