TTableModel

Interface between tabular data and a table viewer.

Inheritance

Level	Ancestor	Description
1	TObject	Ultimate ancestor in a class hierarchy
2	TBaseObject	A base class for objects that can be used instead of `TObject`.
3	TReferenceCountedObject	Object that keeps track of the number of times it is referenced from other objects
4	TTableModel

Description

Tabular data consists of three major components: rows, columns and cells. Rows represent the vertical dimension, columns represent the horizontal dimension and cells represent the actual values for every combination of row and column. A descendant should at least implement GetRowModel, GetColumnModel and GetCells. Both dimensions are treated equally which means you can create tables with both a large dynamic amount of columns and and a large dynamic amount of rows which makes a TTableModel suitable for representing matrices as well as relational data.
