Problems filtering results on post (using tablepress and code snippet)

I’m working on a task where I’m create a database. I’m using tablepress for the data which isn’t the problem.

I’m using the code below to allow me to use a shortcode on each post so I can do some filtering. Problem is the filtering isn’t working.

function dynamic_tablepress_by_slug_shortcode($atts) {
    $atts = shortcode_atts(
        array(
            'table_id' => '',
            'filter_column' => '0',
        ),
        $atts,
        'dynamic_table'
    );

    $slug = get_post_field('post_name', get_post());

    if (!$slug) {
        return '<p><strong>Error:</strong> Could not determine post slug.</p>';
    }

    $shortcode = '[table id="' . esc_attr($atts['table_id']) . '" filter="' . esc_attr($slug) . '" filter_columns="' . esc_attr($atts['filter_column']) . '" datatables_sort="false"]';

    return do_shortcode($shortcode);
}
add_shortcode('dynamic_table', 'dynamic_tablepress_by_slug_shortcode');

However, I still get the entire unfiltered table. I’m using this shortcode in my post.

[dynamic_table table_id="1" filter_column="0"]

Any idea what may be the cause of the problem?

I’ll crosspost on the fixing wordpress page
