v7: Column max width

[michaelhays]

In Prisma Studio v7, columns do not have a maximum width, so columns with a lot of data (especially JSON columns) are extremely wide.

Hey 👋

Thank you! 🙏

What would be a reasonable max width?

Looks like 200px is the minimum, perhaps 400px would be a good maximum?
