Allow default values on creating new table row

Description of the limitation and why it is relevant to address

As a developer, upon creating a new row in my table I would like it to be automatically populated with a default set of data instead of being blank.

Submitter proposed design (optional)

In addition to the default attribute, a row_default could be added as an option in which I would define what this data should be.

Current workarounds

None
