I'm using custom tables to store my data. I'd like to use the rwmb_{$field_id}_html or rwmb_{$field_type}_html filter to adjust the output in dashboard. However the filter is never called when using custom tables.

How must I do this?

Hi Paul,

Yes, you can use this filter for any field, it is the HTML input of the field and is not affected by the value of the field (saved in a custom table or not).
```
add_filter( 'rwmb_fieldID_html', function( $field_html, $field, $meta ) {
    $field_html .= '<p>Add your HTML code here</p>';
    return $field_html;
}, 10, 3 );
```

Yup you're right, I was doing it wrong 🙂

I noticed that the filter isn't used when the field is part of the post list table.
Is it correct that I can only change the output there by using MB Admin Columns and creating a custom class (class Prefix_Custom_Admin_Columns extends \MBAC\Post {})?

Hi,

In the admin columns, you can use the filter rwmb_the_value to customize the output value. Please read more here https://docs.metabox.io/filters/#rwmb_the_value
