Hi All,
I am creating a list of map, in the map i am specifying both column and values dynamically. i could able to display the data using the display tag.but i could not do the sorting on each columns.

I am wondering how to enable Sorting on each column of the map.

note: i could find sortable column only in the <display:column ..> tag,. but i cannot use this in this case because, i don't know how many columns would i display each time.

following is the sample code, i am using.
List listOfSearchValue = new ArrayList();
for(int i=0; i <10; i++)
{
SortedMap sortedMap = new TreeMap();
sortedMap.put("name","name_" + i);
sortedMap.put("address","address_" + i);
sortedMap.put("city","city_" + i);
sortedMap.put("state","state_" + i);
listOfSearchValue.add(sortedMap);
}
request.setAttribute("SearchResult", listOfSearchValue);

<display:table name="SearchResult" id= "result" requestURI="refferencePaResponseListPopulateAction.do" pagesize="15" sort="list" class="displaytablestyles" >
</display:table>

please help me to find a way to sort columns name, address, city and state in the above example.

Thanks
Guna
