  ColumnModel columnModel = new ColumnModel(new ColumnConfig[]{
                new ColumnConfig() {                        
                        setId("change");
                        setHeader("Change");
                        setWidth(75);
                        setSortable(true);
                        setDataIndex("change");
                        setRenderer(new Renderer(){
public String render(Object value, Record record, int rowIndex, int 
colNum) {
              if (((Float) value).floatValue() < 0) { } 
                      else { }
                }
              });

Override getRowClass in GridView. See sample :

http://gwt-ext.googlecode.com/svn/trunk/site/samples/Showcase/Showcase.html#rowR
enderingGrid

 grid.setView(new GridView() {  
     public String getRowClass(Record record, int index) {  
         float price = record.getAsFloat("price");  
         if(price <20) {  
             return "yellowClass";  
         } else if (price < 40) {  
             return "orangeClass";  
         } else if (price < 80) {  
             return "blueClass";  
         } else {  
             return "";  
         }  
     }  
 });
