Thank you for your post into the forum.
Unfortunately SQL Dependency Tracker at this time will not inform on dependencies on columns within a table. Nor will it inform on the data types used.
I know that a feature request is already in place to have SQL Dependency Tracker inform upon the dependencies on columns.
However I will submit a feature request to include information on the data type used, if this request has not been submitted previously.
We have another product that may help you, called SQL Doc. As the product name suggests, this product will generate a document in an easy to read HTML or a .chm file. SQL Doc will inform on dependencies between objects and for tables detail the column names with the data type used.
