### 6.6.11. < rich:subTable > available since 3.0.0

expand all

#### 6.6.11.1. Description

The component is used for inserting subtables into tables with opportunity to choose data from a model and built-in Ajax updates support.

Figure 6.39. <rich:subTable> element

#### 6.6.11.2. Key Features

- Completely skinned table rows and child elements

- Possibility to insert complex columnGroup subcomponents

- Possibility to combine rows and columns inside

- Possibility to update a limited set of rows with Ajax

#### 6.6.11.3. Details of Usage

The <rich:subTable> component is similar to the <h:dataTable> one, except Ajax support and skinnability. One more difference is that the component doesn't add the wrapping <table> and <tbody> tags. Ajax support is possible, because the component was created basing on the <a4j:repeat> component and as a result it could be partially updated with Ajax. The "ajaxKeys" attribute allows to define row keys which are updated after an Ajax request. You can find an example which demonstrate the usage of the "ajaxKeys" attributes for data iteration components in the RichFaces Cookbook article.

The component allows to use "header" and "footer" facets for output. See an example for <rich:dataTable> component.
