How can I format the content in horizontal tabular form?
Do you really care to have tables in the semantic meaning of it?
I mean, you can just print your fields to divs and use float: left for the 3 content elements and for the labels print it manually on a div on the header.

Might not be the most elegant solution but will work and be easier than making it with panels...

The best way to do it would be to print
First Field: Label | Line 1 | Line 2 | Line 3
Second Field: Label | Line 1 | Line 2 | Line 3
But that's not how Views works.

You could also retrieve all the information in a custom module and then manage it however you want. But then, you wouldn't need to use Views module...
