Predefined Table Fields Per Tab In A Form

I am trying to find a simple method to have predefined table fields per Tab in a form
OR
Fill in multiple table fields per control

IE: If I click a check box, option from a drop-box, or Fill in a text-box when that information gets entered into the table the results will be:

Primary Category
Sub Category #1
Sub Category #2
Input

FOOD
_____
FRUIT
APPLE

FOOD
_____
VEGETABLE
SPINACH

The red will be automatically inserted based on what I chose for the "Sub Category #2" drop-down. The green will be what I typed in.
