table -api-title

[qhl123456]

• I have searched the issues of this repository and believe that this is not a duplicate.

What problem does this feature solve?

I noticed that the title of the table does not support a simple string form, but supports functions or slots. I would like to know why a simple string form was not added at the beginning of the design

What does the proposed API look like?

I wish could add a separate string type
