 Replying to [comment:3 desrosj]:

 base class, but the other two filters do exist in `WP_List_Table` today.
 So I could see adding this filter.

 @desrosj Has there been any progress on this? I found this thread in my
 own search for a solution. I am trying to add a custom column to a custom
 table of an installed plugin. I too followed the same article as @madvic
 https://make.wordpress.org/docs/plugin-developer-handbook/10-plugin-
 components/custom-list-table-columns/#output-table-cell-contents

 I was able to add the column to the table with

 {{{
 manage_{$this->screen->id}_columns
 }}}

 using the screen ID of that plugin's table page. However, as stated, the

 {{{
 manage_{$screen->id}_custom_column
 }}}


 doesn't seem to exist, so my content won't display in the columns.

 As this table isn't a custom post type, or any of the other class
 available as stated by @SergeyBiryukov , I'm unable to add content with
 any of those options. This is the screen object readout for that table's
 page, and you can see that there's no post type, taxonomy, etc for me to
 use, and since {$screen->id} doesn't work, I'm at a loss:


 {{{
 WP_Screen Object ( [action] => [base] => memberpress_page_memberpress-
 members [columns:WP_Screen:private] => 0 [id] =>
 memberpress_page_memberpress-members [in_admin:protected] => site
 [is_network] => [is_user] => [parent_base] => [parent_file] => [post_type]
 => [taxonomy] => [_help_tabs:WP_Screen:private] => Array ( )
 [_help_sidebar:WP_Screen:private] =>
 [_screen_reader_content:WP_Screen:private] => Array ( )
 [_options:WP_Screen:private] => Array ( )
 [_show_screen_options:WP_Screen:private] =>
 [_screen_settings:WP_Screen:private] => [is_block_editor] => )

 }}}

 Being able to add content to the column in this table would be a huge
 help. I'd love to know if there is a way to do this yet. Thank you!
