Renders the header of a
Repeater tag. This header may contain any any HTML markup that
can be rendered to a page. In the case of starting a table, ordered list, or unordered list,
the HTML elements <table>, <ol>, and <ul> could respectively be rendered inside
the body of this tag.
There is no data item present at the time that the <netui-data:repeaterHeader> renders (because
the iteration of the <netui-data:repeater> tag has not yet begun), so tags in the body can not
reference the ${container...} JSP EL implicit object to access the current item in
the data set, though other databinding contexts are available.
The footer tag is rendered exactly once at the beginning of repeater rendering.
For example, the following sample renders the data set as an HTML table. The table has two columns, "index" and "name",
and each iteration over the data set is rendered a row of the table. The <netui-data:repeaterHeader>
tag renders once, before the iteration has begun. It renders an opening HTML table tag and
two header rows for the table.
