Dear DraganSE,
Good day to you!
I hope you are doing well. Thanks for reaching out to our Microsoft Community Forum. We will be happy to help you.
I’m sorry to hear that you’re unable to find the Table Shape in the Basic Shapes stencil in Visio. Since you mentioned that you are using Visio 2019 and are unable to locate the shape, I sincerely apologize for any inconvenience this may have caused.
I’d like to inform you that, in this community environment, we don’t have access to Visio 2019 to test its features directly. Given this, I kindly suggest posting your concern in the appropriate support channel, where experts familiar with Visio 2019 may be able to assist you further.
I believe there might still be ways to troubleshoot this issue from their end, and I hope they can provide you with a helpful solution. Microsoft has a specific channel Visio Management - Microsoft Q&A. You may ask the question in this community. I recommend you post a new thread (click "Ask a question" and add the tag Visio Management in the Tags field) there for expert help.

That support team there will have the correct channel and resources to help you.
The reason I emphasize avoiding incorrect information is to ensure clarity, accuracy, and reliability in communication. Providing precise and well-detailed responses fosters trust and helps prevent confusion or misunderstandings. When information is incorrect or ambiguous, it can lead to errors, wasted time, and frustration for those relying on it.
I do apologize for any inconvenience.
Thank you for your understanding. Your cooperation and contributions are greatly appreciated.
Kind Regards,
Nahid Sultan
