How to add column descriptions (comments) in Doctrine2

You can add a comment to a column name or entire table with the "options" argument to the annotation; eg:
/**
 * @ORM\Column(type="string", options={"comment":"The string to show in the dropdown "})
 */
for a column, or for a table:
/**
 * @ORM\Entity
 * @ORM\Table(name="application", options={"comment":"Funding applications"});
 */
Note however this will not add comments to an existing table or column, you have to delete the table from the DB and rebuild it. If it's just adding comments, you could rename the table, create the new table, and import data from the original.
