	List<CellData>[] listData;
	CellData[][] cover;
	public GridSplitImpl(List<CellData>[] listData,CellData[][] cover){
		this.listData=listData;

	}
	public boolean isVisible(int row, int column) {
		if(row>=listData.length||row<0) return true;
		return cover[row][column]==null;
	}

	public int spanCol(int row, int column) {

			return 1;
