This topic introduces guidelines and conventions for implementing ITableProvider, including information about properties, methods, and events. Links to additional references are listed at the end of the overview.
The TablePattern control pattern is used to support controls that act as containers for a collection of child elements. The children of this element must implement ITableItemProvider and be organized in a two-dimensional logical coordinate system that can be traversed by row and column. This control pattern is analogous to IgridProvider, with the distinction that any control implementing ITableProvider must also expose a column and/or row header relationship for each child element. For examples of controls that implement this control pattern, see Mapeamento de Padrão de Controles para Clientes de Automação de IU.

Implementation Guidelines and Conventions
When implementing the Table control pattern, note the following guidelines and conventions:
Access to the content of individual cells is through a two-dimensional logical coordinate system or array provided by the required concurrent implementation of IGridProvider.
A column or row header can be contained within a table object or be a separate header object that is associated with a table object.
Column and row headers may include both a primary header as well as any supporting headers.
Observação
This concept becomes evident in a Microsoft Excel spreadsheet where a user has defined a "First name" column.This column now has two headers—the "First name" header defined by the user and the alphanumeric designation for that column assigned by the application.
- See Implementando o Padrão Controle Grid de Automação de Interface de Usuário for related grid functionality.
