manage_(screen_id)_columns хук-фильтр . WP 3.0.0

Filters the column headers for a list table on a specific screen.

The dynamic portion of the hook name, $screen->id, refers to the ID of a specific screen. For example, the screen ID for the Posts list table is edit-post, so the filter for that screen would be manage_edit-post_columns.
