Hmmm thanks for a fast reply.
How is that suppose to work?
I have made a little example but I cannot get it to work.
In jsp-file
<%
Map<String, String> map = new HashMap<String, String>();
for (int i = 0; i < 10; i++) {
map.put("a", "a" + String.valueOf(i));
map.put("b", "a" + String.valueOf(i));
map.put("c", "a" + String.valueOf(i));
}
request.setAttribute("map", map);
%>
<display:table name="map" export="true" pagesize="10000"
defaultorder="descending">
<display:setProperty name="export.excel.filename" value="test.xls"/>
<display:column property="map(a)" title="A*"/>
<display:column property="map(b)" title="B*"/>
<display:column property="map(c)" title="C*"/>
</display:table>

I saw your question when it was originally posted but couldn't get my
head round what you were trying to do and hoped someone else would.
Have you tried something like this?
<display:table name="datas">
<display:column property="key" title="Key"/>
<display:column property="map(b1)" title="B1"/>
<display:column property="map(b2)" title="B2"/>
<display:column property="map(b3)" title="B3"/>
<display:column property="map(b4)" title="B4"/>
</display:table>
The documentation shows this way of specifying mapped properties here
<http://displaytag.sourceforge.net/11/tut_sources.html> and although
this is for the name attribute of the <display:table> tag it may also
work for the property attribute.
