[Typo3] extra fifth layout table type

[Bas van der Togt]

Hello list,

How can I add a fifth type to the table element?
Now default and types 1-3 exist, and I like to implement odd and even 
color adjustments in a user-friendly way by just selecting a fifth layout.

I'm aware that this is possible with some extensions, but I like to do 
it this way without adding additional code within the table element 
itself (class id) or installing extension which support this.

Thanks and cheers,
Bas van der Togt
