The `__tablename__` attribute tells SQLAlchemy the name of the table to use in the database for each of these models.

### Create model attributes/columns

Now create all the model (class) attributes.

Each of these attributes represents a column in its corresponding database table.

We use `Column` from SQLAlchemy as the default value.

func (idx Index) Table() string {
	return idx.TableName
}

// Name return the name of the index.
func (idx Index) Name() string {
	return idx.NameValue
}

// Columns return the columns of the index
func (idx Index) Columns() []string {
	return idx.ColumnList
}

// PrimaryKey returns the index is primary key or not.
func (idx Index) PrimaryKey() (isPrimaryKey bool, ok bool) {
