Hi Siddharth,
Thanks for posting your query here.
In order to access table storage you've have a database. I hope you've one.
In management portal go to databases and dashboard, on the right side you've manage URL option.
Click on the URL and login with your credentials and you'll have all the options. You should be able to create and view the tables.
Request you to provide the URL....
Let me know if that helps.
Best Regards,
Sadiqh Ahmed
