How-to create a table and its according history table in tsql

The main principle -

recreate the table from ssms
with TableNameHistory
add A TableNameHistoryId with the identity
add an Action Column - specifies what is the action performed on the table to track
add an SqlLogin Column - specifies the sql login performing the action
add an UpdateWhen column - specifies the time of the update ( here Update means the UPDATE , DELETE , INSERT actions )

Copy paste this triggers and replace the name of the "Feature" table with the name of your table
+ replace the corresponing columns.

The whole thing could wrap up in a single DDL trigger for CREATE_TABLE. If you have done it , please share a code ...
