You don't need to define any columns inside the <display:table> element if you want all the data displayed. It might be smart enough to handle it. Otherwise you'll have to force your array into a more suitable form such as an array of Map objects, each Map representing one row and created from the 2nd dimension of your 2D array.

I want to display columns that does not exist as properties in a class. Instead I have stored the data in a map. Let's say I have the following data that I want to display: key col value a1 b1 2 a2 b1 3 a2 b2 6 a3 b2 2 a3 b1 5 a4 b3 5 .. .. a2000 b3 1 a2000 b20 3 So the a values range from 1- to ??? ( in the example 2000 ) and the b values range from 1-??? ( in the example 20 ). I want to display the b values as columns with so the example will be: key b1 b2 b3 ... b20 a1 2 a2 3 6 a3 5 2 a4 5 ... a2000 1 3 So adding a new b-value in the datatable would lead to adding a column in the displaytag table. My class storing the data would be something like this: class DataHolder{ private String key; // the unique a-value private Map<String, Integer> map; //containing all the b values for the key. public String getKey(){ return key; } public void setKey(String key){ this.key = key; } public String getMapValue(String col){ Integer value = map.get(col); return value; } public Map getMap(){ return map; } public void setMap(Map map){ this.map = map; } public List getColumns(){ List retList = new ArrayList(); Object keys[] = map.keySet().toArray(); for (int i = 0; i < keys.length; i++) { Object o = map.get(keys[i]); retList.add(o); } return retList; } } Ok, so using this class I want to create the outputtable in displaytag.. how can I do this? As of my understanding I can only display properties that exist in the class. In my example the property key, via the <% List datas = BusinessFacade.getClassDatas(); // returning a list of all the ClassData's... request.setAttribute("datas", datas); %> <display:table name="datas" export="false" sort="list" pagesize="10000" defaultorder="descending"> <display:column property="key" title="Key" sortable="true" headerClass="sortable"/> <!--how to display the columns here???--> </display:table> /Simon ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
