Coupling two tables in Access and setting as subform source

OK this might be an easy answer, but I'm still learning on Access.  I have Access 2003 database with a main form with a source table (we'll call TABLE 1).  Contained within this main form is a subform with a separate table source (TABLE 2).  I have reached the 255 max number of entries in TABLE 2, but I still need to add more fields to this table as well as on the subform.  The only thing I could think of is to somehow create another table with these additional items and somehow couple it to TABLE 2.  But since the subform can only link to one table, I wasn't sure how to accomplish this.  Thoughts?

Hello janderscu,

With respect, why so many fields?  Having more than a few dozen fields is usually a sign of suboptimal

255 fields in any one table is somewhat excessive.

However, you can create a 2nd table - same structure - same primary key ... and create a One To One relationship between the two tables.

Then, for the subform Recordsource, create a query which joins the two tables together via the Primary Key field.

We are collecting patient physical exam measures and that is just what we need to collect, but DatabaseMX has a great idea to split it up and set the query as the form source.  I will go that route.  Thanks.
