Thanks John, I modify id column as you said,like follows:
<display:table name="datalist" requestURI="/demo.do" id="pl" pagesize="10">
<display:column property="id" title="ID" headerClass="sortable"
><%=pageContext.getAttribute("pl_rowNum")%></display:column>
<display:column property="name" sortable="true" headerClass="sortable" />
<display:column property="score" sortable="true" headerClass="sortable" />
</display:table>
when I run above code first,it shows following result:
id name score
1 Jack 80
2 Kate 90
3 Mary 75
But when I click score column,it shows following result:
id name score
3 Mary 75
1 Jack 80
2 Kate 90
I hope my sort result is following:
id name score
1 Mary 75
2 Jack 80
3 Kate 90
Why id value changed? How to keep pl_rowNum value from 1-3 whether sort or not?
An example code is better.
Thanks in advance
Best regards,
Edward

In this case, it seems that you don't really want to display the IDs of the
items in the collection, but rather just the row number in the table. For this,
you can use the <tableId>_rowNum implicit object (pl_rowNum in your example).
Look at the example on page 26 of the project documentation PDF.

I want to display table list,so I use displaytag,my code is follows:
<display:table name="datalist" requestURI="/demo.do" id="pl" pagesize="10">
<display:column property="id" title="ID" sortable="true"
headerClass="sortable" />
<display:column property="name" sortable="true" headerClass="sortable" />
<display:column property="score" sortable="true" headerClass="sortable"
/>
</display:table>
When it run,it show follow result:
id name score
1 Jack 80
2 Kate 90
3 Mary 75
Then I click score column to sort,it shows:
id name score
3 Mary 75
1 Jack 80
2 Kate 90
