You can delete a field from a table.
 Caution: |
|---|
| Deleting a field from a table deletes information about the field, including the field's default value, rule definitions, and caption. If an index key or trigger expression references the field, the expressions become invalid when the field is deleted. The invalid index key or trigger expression does not generate an error until run time. |
