	if (isCellEditable(row, column)) {
		editCellAt(row, column);
		Component editorComponent = getEditorComponent();
		if (editorComponent != null) {
			if (editorComponent instanceof JComponent) {
				JComponent jComponent = (JComponent) editorComponent;
				if (!jComponent.hasFocus()) {
					jComponent.requestFocusInWindow();
				}
				return true;
