    Default Grid row with a CheckBoxCell has wrong height

    Grid row with a CheckBoxCell has wrong height


    The row's height is higher than usual.

    Code:
    package es.inaer.taller.client;
    
    import java.util.ArrayList;
    
    import com.google.gwt.cell.client.TextCell;
    import com.google.gwt.core.client.EntryPoint;
