Hi nashley, thanks for your question!
You can definitely create a new worksheet after creating a new table. Go to your current worksheet and open the left panel by clicking on the worksheet icon on the very left of your screen. You should either see a panel appear showing the current tables in your worksheet or a list of your current worksheets. If you see the tables list, simply click on the "sheet" icon in the upper right of the panel and you should be able to manage your worksheets there.
