public class CellVector
extends java.util.Vector<Cell>

An object of the type CellVector is associated with every cell-container, i.e., a Row or a Column object. It is basically a vector to store the cells that are added to the associated cell-container. However, depending upon the alignment of the row or the column, it transparently inserts suitable flexible gaps whenever a cell is added to it. Thus for example, if the row or the column is justified, it automatically adds a flexible gaps whenever a cell is added to the associated cell-container after the first or before the last addition.
