Joining Multiple Data Tables

[#1]

Hiya!

I am having issues merging these two data tables. For some reason, every way I merge them, I end up with 60,000+ rows. I know I should be able to just join the tables or update the information from table two into table one, but I am stuck. I thought of trying the Query builder, but I am confused, and I also do not know how to code so I cannot join the tables that way. 

Thoughts?
