+ * SECTION:atktable
+ * @Short_description: The ATK interface implemented for UI components
+ * which contain tabular or row/column information.
+ * @Title:AtkTable
+ *
+ * #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". Those cells should
+ * implement the interface #AtkTableCell, but #Atk doesn't require
+ * them to be direct children of the current #AtkTable. They can be
+ * grand-children, grand-grand-children etc. #AtkTable provides the
+ * API needed to get a individual cell based on the row and column
+ * numbers.
+ *
+ * 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.
+ *
+ * Note for implementors: in the past, #AtkTable required that all the
+ * cells should be direct children of #AtkTable, and provided some
+ * index based methods to request the cells. The practice showed that
+ * that forcing made #AtkTable implementation complex, and hard to
+ * expose other kind of children, like rows or captions. Right now,
+ * index-based methods are deprecated.
