Hi, James,

Thanks for a good feedback!

Please, see the screenshots in this blog post, where you can see how to resize columns.

Nope, we never needed vertical lines, so there is no way to see it.
Please, let us know more details about it. Do you need it as an option in the Database Widget?
We may want to add such settings, it will be a part of our ‘database widget improvements’ task.

Thanks!
