adding a table to a custom test

I'm trying to  get the format of a new custom test I'm writing correct.

What I want it to look like is:

                                                Title

                Header                 Header                 Header
                Field                      Field                      Field
                .                               .                               .
                .                               .                               .


                                Trailing  info

When I put in html tags, I get a full page of blank under the "History" button, then my output. Also, my trailing info comes first.

So how can I add a table into the status message of the xymon command?

My servers are 4.3.10, the clients are 4.2.3 or 4.3.4.
