Description

AtkTable should be implemented by components which present elements ordered via rows and columns. It may also be used to present tree-structured information if the nodes of the trees can be said to contain multiple "columns". Individual elements of an AtkTable are typically referred to as "cells", and these cells are exposed by AtkTable as child AtkObjects of the AtkTable. Both row/column and child-index-based access to these children is provided.

Children of AtkTable are frequently "lightweight" objects, that is, they may not have backing widgets in the host UI toolkit. They are therefore often transient.

Since tables are often very complex, AtkTable includes provision for offering simplified summary information, as well as row and column headers and captions. Headers and captions are AtkObjects which may implement other interfaces (AtkText, AtkImage, etc.) as appropriate. AtkTable summaries may themselves be (simplified) AtkTables, etc.
