Sheet Multi Header

For more complex headers, which can span over columns and/or rows use a <f:facet name="header">in the sheet. The facet could be filled with <tc:out/> tags to set the names of the header. Such an output field tag may also contain <tc:gridLayoutConstraint columnSpan="..."/> or <tc:gridLayoutConstraint rowSpan="..."/> to set a span over columns or rows.
