Check if Table has been created

Table check

We need to be able to check and see if a table has been created so that we don't overwrite the file every time.

This feature will come in handy once we need to append data, and make it persist!

• A user creates a table
• Then the user adds data
• When the user reads the table
• All the data the user wrote should be there
• Then the user can be sure the data is there forever
• Until the table is dropped or overwritten

Nice fix!
