[TYPO3-english] Correct use of tablenames field in mm tables

[Guillermo R. Oramas J.]

Hello.

I noticed there is a field "tablenames" that is used in the mm tables.

I looked for information but it appears that there is not much.

I have two very similar tables that have a mm relation with a third
table, so I created two mm tables, but I guess that with this
"tablenames" is possible to have only one.

Could someone guide me through the correct use of that field?

Thanks a lot.
