Summary
In this module, you learned how to create a table extension with the ttableext snippet. A table extension is used to add fields to an existing table. You can also use table extensions to modify properties of existing fields.
Not all properties of the Table object are available on the TableExtension object.
When you add extra fields to an existing table, you need to make sure that you aren't using the same numbers or names of existing fields. Use prefixes or suffixes to uniquely identify your fields.
