Add Custom Columns

I’m circling back to a post that I submitted a little over a year ago about adding custom columns to the report:

To show custom column you have to extend it using filter.

To add new column header, use the filter:
faulh_admin_get_columns

To show the value, use the filter:
manage_faulh_admin_custom_column

Note: These filters are not officially released yet. The name of these filters may be changed in future version and even these filters can be removed. So you have to change your code accordingly.

Are those filters still valid? I’m having problems with them – which I”m sure is due to my skill level, lol. How can I add an additional column to the page?

Thanks!
