I don't think you can.
Why would you want to do that?
Do you mean you would like to see tabular data and composite data displayed
as a simple string?
If you use JConsole from Java 6 then you could write your own plugin to
display your MBeans in whatever form you like...
In this post I explained how I was able to write a beanshell plugin by taking
example on the JTop demo.
