hello, i need to populate  a GridView dynamically, i've created the colums already, but i don't know how to fill the rows???

I 've tried with Cells, but i don't find a function to put the label i want to show,

 i got the following code:

       tabla=new HtmlGridView();
        HtmlOutputText tit=new HtmlOutputText();
        tit.setValue("Monitoreo a Caja");
        tabla.setHeader(tit);
       
        com.infragistics.faces.grid.component.Column col1=new com.infragistics.faces.grid.component.Column();                       
        HtmlOutputText enc1=new HtmlOutputText();
        enc1.setValue("Header 1");
        col1.setHeader(enc1);
        tabla.getColumns().add(col1);
       
        com.infragistics.faces.grid.component.Column col2=new com.infragistics.faces.grid.component.Column();
        HtmlOutputText enc2=new HtmlOutputText();
        enc2.setValue("Header2");
        col2.setHeader(enc2);   
        tabla.getColumns().add(col2);

                        
        HtmlOutputText valor1=new HtmlOutputText();
        valor1.setValue("valor1");        
        HtmlOutputText valor2=new HtmlOutputText();
        valor2.setValue("valor2");              
        com.infragistics.faces.grid.component.RowItem ren1=new com.infragistics.faces.grid.component.RowItem();
       
        com.infragistics.faces.grid.component.Cell cel1=new com.infragistics.faces.grid.component.Cell();  
        com.infragistics.faces.grid.component.Cell cel2=new com.infragistics.faces.grid.component.Cell();

        HOW DO I PUT THE LABEL????????               
                
        ren1.getCells().add(cel1);
        ren1.getCells().add(cel2);
                                                              
        tabla.getRows().add(ren1);

thanks.
