How to change column in migration after creation?

Question

Yii

In a migration, when creating, you can specify for a column, for example

$this->string()->after('column2')->defaultValue('test')->notNull()

But how can you change all this? Of the methods for changing a column, I found only $this->renameColumn. What about everything else? For example, set a position or a default value that was not initially set ... How can I do all this?
