Java – how to merge grid cells in GXT

I wonder if I can merge cells in the GXT grid like this:

I think I have to overwrite the renderer, but I can't find one Can someone tell me how to use GXT 3.0?

Solution

This is how I edit the cells in the grid in GXT 3 In this example, I just add a div, so I can add an ID for selenium test:

ColumnConfig<LessonOFY,String> name = new ColumnConfig<LessonOFY,String>(lessonProperties.name(),250,i18n.lessonName());

AbstractCell<String> c2 = getTestingLabel(GAE_ID_CONSTANTS.IDS.LESSON_GRID.toString());

name.setCell(c2);


public static AbstractCell<String> getTestingLabel(final String label) {
    AbstractCell<String> c2 = new AbstractCell<String>() {

        @Override public void render(com.google.gwt.cell.client.Cell.Context context,String value,SafeHtmlBuilder sb) {

            value = "<div id=\"" + label + "\">" + value + "</div>";
            sb.appendHtmlConstant(value);
        }

    };
    return c2;
}

Value is just the value set in the grid

Now that you have raised the question, I really want to do the same thing Please let me know if you like Please!
