How to add classes/id to column header?

[iosiflivadaru]

I was wondering what would be the best practice to add classes and id to a column. As you can see below, they are empty and I can't seem to find a way to populate that...

See these methods:

/**
 * Used to set a class on a table header based on the column attribute
 */
public function setTableHeadClass($attribute) : ?string;

/**
 * Used to set a ID on a table header based on the column attribute
 */
public function setTableHeadId($attribute) : ?string;

/**
 * Used to set any attributes on a table header based on the column attribute
 * ['name' => 'my-custom-name', 'data-key' => 'my-custom-key']
 */
public function setTableHeadAttributes($attribute) : array;
