You may also seed your database using the migrate:refresh command, which will also rollback and re-run all of your migrations. This command is useful for completely re-building your database:
您还可以使用 migrate:refresh 命令为您的数据库设定种子，该命令还将回滚并重新运行您的所有迁移。此命令对于完全重建数据库很有用：

If you want to wipe out certain table, then just TRUNCATE that table, and seed it again:
