One small recommended tweak to your response above. In Step 3, instead of selecting “delete” for Column 1, select “hide”.
The reason is that if you use external tools to document and analyze your model (such as my favorite - Monkey Tools), if you delete Column 1, the tools may no longer recognize that table, but they will if you just hide it.
Even if you don’t use any of these tools currently, I think “hide” is the best approach since it still preserves your option to use them in the future.
