                    throws IOException
Renders either the header or the footer facets for the UIData component and all the child UIColumn components, as a THEAD or TFOOT element containing TR (row) elements.

If there is a header or footer attached to the UIData then that is rendered as a TR element whose COLSPAN is the sum of all rendered columns in the table. This allows that header/footer to take up the entire width of the table.

If any child column has a header or footer then a TR is rendered with a TH cell for each column child.

Parameters:
facesContext - the FacesContext.
writer - the ResponseWriter.
component - the UIData component
header - whether this is the header facet (if not, then the footer facet).
Throws:
IOException - if an exception occurs.

determineHeaderFooterTag

protected String determineHeaderFooterTag(FacesContext facesContext,
                                          UIComponent component,

Parameters:
header -
uiComponent -
Returns:
boolean

determineChildColSpan

protected int determineChildColSpan(UIComponent uiComponent)
Calculate the number of columns the specified child component will span when rendered.

Normally, this is a fairly simple calculation: a UIColumn component is rendered as one column, every other child type is not rendered (ie spans zero columns). However custom subclasses of this renderer may override this method to handle cases where a single component renders as multiple columns.

protected void renderTableHeaderRow(FacesContext facesContext,
                                    ResponseWriter writer,

                                    String headerStyleClass,
                                    int colspan)
                             throws IOException
Renders the header row of the table being rendered.

Parameters:
facesContext - the FacesContext.
writer - the ResponseWriter.
component - the UIComponent for whom a table is being rendered.
