The Text Block element is the most appropriate choice. It is specifically designed as a display element to show read-only information within an OmniScript. It fully supports HTML, which is necessary for creating the required table structure. Furthermore, it can dynamically render data from the OmniScript's data JSON using merge codes (e.g., %FirstName%). This combination of being read-only, supporting HTML formatting, and using merge codes directly addresses all aspects of the developer's requirement.
