If you add an
id
attribute the table tag makes the object corresponding to the given row available in the page context so you could
use it inside scriptlet code or some other tag. Another implicit object exposed by the table tag is the row
number, named
id
_rowNum
.
These objects are saved as attributes in the page scope (you can access it using
pageContext.getAttribute("id")
). They are also defined as nested variables (accessible using
<%=id%>
), but only if the value of the id atribute is not a runtime expression. The preferred way for fetching the value
is to always use pageContext.getAttribute().
If you do not specify the
id
attribute no object is added to the pagecontext by the table tag
This is a simple snippet which shows the use of the implicit objects created by the table tag with JSTL.
<display:table id="row" name="mylist">
<display:column title="row number" >
<c:out value=""/>
</display:column>
<display:column title="name" >
<c:out value=""/>
<c:out value=""/>
</display:column>
</display:table>
