I added this taglib at the beginning of my jsp

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

and i added below code

<display:table name="studentList" id = "student" cellspacing="1px" class="center">

<display:caption class="caption"><b>Student Mark List</b></display:caption>

<c:choose>
            <c:when test="${mark>='80'}">
                <c:set var="css" value="tableColumnGreen"/>
            </c:when>                                              

            <c:otherwise>
                <c:set var="css" value="tableColumnRed"/>
            </c:otherwise>
 </c:choose>
<display:column title="Student Name" property="name" class="${css}"> </display:column>
<display:column title="Student Mark" property="mark" class="${css}"></display:column>
<display:column title="Student Result" property="result" class="${css}"> </display:column>

This helped me.Thanks for everyone.

I would have liked to find out how to apply the style at the tag instead of at each tag but this solution gets me moving again and I appreciate it. — k-den, Oct 23 '13 at 15:59
