Hey there, thanks for reaching out! :) Currently, there is no feature in Clay that allows you to select what tables you want to show to which users in your space. This means that you cannot create private tables or workspaces that are hidden from other team members, similar to a personal page in Notion. I'll record this message as feedback for our product roadmap.
If there's anything else I can assist you with, please let me know! ๐
Have a great Monday,
Daniel
