You will notice the CellTable uses a ResourceBundle, which means all the css styles get obfuscated ... this makes it more difficult to override styles.
The CellTable constructor will actually allow you to override the default ResourceBundle. So first, you need to create your own resource bundle like this:
public interface CellTableResources extends Resources {
public CellTableResources INSTANCE =
GWT.create(CellTableResources.class);
/**
* The styles used in this widget.
*/
@Source("CellTable.css")
CellTable.Style cellTableStyle();
}
Then you need to create your own CSS file. I recommend copying the CellTable style directly into your project and use that as a starting point. You can find it here:
http://code.google.com/p/google-web-toolkit/source/browse/trunk/user/src/com/google/gwt/user/cellview/client/CellTable.css
Make sure the style is injected first, and then you just feed it into the CellTable's constructor like this:
CellTableResources.INSTANCE.cellTableStyle().ensureInjected();
myCellTable = new CellTable<T>(Integer.MAX_VALUE,CellTableResources.INSTANCE);
Specifically, you'll want to tweak these styles:
- cellTableKeyboardSelectedRow
- cellTableKeyboardSelectedRowCell
- cellTableSelectedRow
- cellTableSelectedRowCell
- cellTableKeyboardSelectedCell
It is important to note that the cell table differentiates between the 'selected row' and the 'keyboard selected row'. The selected row is the actual row selected (ie via SelectionModel). The keyboard selected row refers to what is highlighted when the user is pressing the up / down key, but does not mean the row is actually selected (if that makes sense).
