How to get index in jstl display table

I have display table like below

<display:table name="sample" id="sample" class="display-table" style="width:100%;">

</display:table>

Now I want to get index of loop like for first element 0 for second 1 and 2,3,4... go on. How it is possible with display table.

For just reference we can do like this in JSTL forEach loop with help of varStatus variable like below

<c:forEach items="${sample}" var="clm" varStatus="status">
     ${status.index}
</c:forEach>

So is this possible with display table?

display table tag implicitly exposes row number named id_rowNum where id is specified in display table tag.

In your scenario:

    <display:table name="sample" id="sample" class="display-table" style="width:100%;">
        <display:column title="Row Number" >
          <c:out value="${sample_rowNum - 1}"/>
        </display:column>
        ...
    </display:table>

Also make sure to include core tag as:

   <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

You can find more information about implicit objects of display table tag here.
