如何获取实体表名？（ex：member-pre-sale-detail）我要设置表评论

// Seeder: Clear & set Comment
export default class ClearAllSeed implements Seeder {
    public async run(factory: Factory, connection: Connection): Promise<void> {

        const deleteEntities = [
            {table: OrderHead, comment: '訂單/主表'},
       ]

       for(const entity of deleteEntities){
            await connection
                .createQueryBuilder()
                .delete()
                .from(entity.table)
                .execute();

            await connection
                // >>>> but table name is MemberPreSaleDetail not member-pre-sale-detail
                .query(`alter table ${entity.table.name} comment '${entity.comment}'`);
        }
   }
}

// Sampel Entity
@Entity('member-pre-sale-detail')
export class MemberPreSaleDetail {
  @PrimaryGeneratedColumn({unsigned: true})
  id?: number;

  @Column({comment: '幾批(整批)', type: 'mediumint', default: 0})
  batchQty: number;
}

预期行为

获取'member-pre-sale-detail'字符串
