Supplier Type category through DFF Table Validation

Greetings dear experts

I'm currently creating a DFF for add an additional category for suppliers. The idea is that according to the supplier type chosen the user can select from DFF list of values a sub-category for that specific supplier but the sub-category list of values depends on what is populated in supplier type. So I created a Value Set with Validation type "table" as shown as follows:

EDIT INFORMATION

But I can't create the specific list of values for this value set so the user can choose from a list of values conditioned to what its stated in "VENDOR_TYPE_LOOK_CODE"
