KQL - Adding a row for each combination of two rows

Question

I have two tables:

• Table 1: ID, blah blah blah blah
• Table 2: Dates

There are a total of 12 dates in Table 2. I want to create a new table where the ID from Table 1 is matched with EACH date from Table 2. Basically, for each ID, there will be 12 rows in the new table. I can't join since there are no matching values between the tables and I tried a union, but I'm unsure how to accomplish what I'm asking.
