Class TableSupport

java.lang.Object
  y.view.tabular.TableSupport

public class TableSupport
extends java.lang.Object

This class is meant to ease working with the table structure of a TableGroupNodeRealizer. If offers methods to add rows and column, modify their position in the row or column hierarchy and change their size. In contrast to the according methods of TableGroupNodeRealizer these implementations do also update the sizes of the row's or column's ancestor containers and move content nodes and bends of the table so that they keep their position relative to the rows and columns they are associated with.
