How to add a user attribute for a table

kevin_f

I'm using BIRT 2.1.1

Now I want to add a customised attribute for a table.
e.g.
<table myAttr="sampleAttri">
....
</table>

I tried "user properties" and "named expressions" in BIRT Properties Editor, but neither works...

Beside, can I add an onclick event for table header?
like:
<table>
<tr>
<th onclick="alert('hello');">
....
</tr>
</table>

Is there any one can help?

I tried BIRT 2.2 and 2.3 and still didn't find a solution to add an user attribute...
