Class TableRenderUtil

java.lang.Object

org.kuali.rice.kns.util.TableRenderUtil

public final class TableRenderUtil
extends Object

This class provides utilities to support the rendering of tables in Kuali without using display tag. Normally, displaytag handles the rendering of Kuali tables on various screens, but there are situations where displaytag is inadequate for the task (e.g. multiple value lookups). In particular, display tag does not handle POSTing of forms when switching between pages and sorting.
