                        throws java.io.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:
    `java.io.IOException` - if an exception occurs.

### hasFacet

    protected boolean hasFacet(boolean header,
                               javax.faces.component.UIComponent uiComponent)

  Parameters:
    `header` -
    `uiComponent` -
  Returns:
    boolean

### determineChildColSpan

    protected int determineChildColSpan(javax.faces.component.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.
