You can view the INDEXES column below where you find a default PRIMARY KEY is set  If it is not set or you want to set any other variable as a PRIMARY KEY then   there is a dialog box below to create an index which asks for a column number  either way you can create a new one or edit an existing one The existing one shows up a edit button whee you can go and edit it and you re done save it and you are ready to go
