Here is my situation: I am trying to filter the content of the title column in my custom post type edit table but I can't get it working.

Here is what I have tried:

add_filter('manage_edit-mycpt_columns', 'replace_title_products');

function replace_title_products() {
    $oldtitle = get_the_title();
    $newtitle = str_replace(array("<span class='sub-title'>", "</span>"), array("", ""),$oldtitle);
    $title = esc_attr($newtitle);
    return $title;  
}

I just want to filter the <span> tags in my title. Could someone help me please?

1. Change post title in post list column

I misunderstood what you wanted - obviously. You can do that like this:

add_action(
    'admin_head-edit.php',
    'wpse152971_edit_post_change_title_in_list'
);
function wpse152971_edit_post_change_title_in_list() {
    add_filter(
        'the_title',
        'wpse152971_construct_new_title',
        100,
        2
    );
}

function wpse152971_construct_new_title( $title, $id ) {
    //print_r( $title );
    //print_r( $id );
    return 'new';
}

Making use of the admin_head-$hook_suffix hook.

2. Replace the table column title

Besides you are not using and overwriting the column table title. Below some exemplary code on how to do it:

1. Based on the manage_{$this->screen->id}_columns hook

   add_filter(
       'manage_edit-post_columns',
       'wpse152971_replace_column_title_method_a'
   );
   function wpse152971_replace_column_title_method_a( $columns ) {  
       //print_r($columns);  
       $columns[ 'title' ] = 'new title';  
       return $columns;  
   }  
   

2. Based on the manage_{$post_type}_posts_columns hook

   add_filter(
       'manage_post_posts_columns',
       'wpse152971_replace_column_title_method_b'
   );
   function wpse152971_replace_column_title_method_b( $posts_columns ) {
       //print_r($posts_columns);
       $posts_columns[ 'title' ] = 'new title';
       return $posts_columns;
   }

Last but not least the following code is handy to get the information you need:

add_action( 'admin_head', 'wpse152619_dbg_dev' );
function wpse152619_dbg_dev() {
    global $pagenow;
    print_r( $pagenow );
    echo '<br>';
    print_r( $_GET[ 'taxonomy' ] );
    echo '<br>';
    $current_screen = get_current_screen();
    print_r( $current_screen->id );
}

I have just done something similar a few hours ago, so my code might not be the best it could be but you need to use 2 hooks to achieve this. As you appear to be using a custom post type from what I saw in your code, these two hooks would be.

manage_post_type_posts_columns()

manage_post_type_posts_custom_column()

I have used the manage_post_type_posts_columns() filter hook to create a new Title column and unset the old one and then the manage_post_type_posts_custom_column() action hook to use my own method for generating the new content/title for this column.

Hope this helps, have added your code in as well...

// Replace your Title Column with the Existing one //
function replace_title_column($columns) {

    $new = array();

    foreach($columns as $key => $title) {
        if ($key=='title') 
        $new['new-title'] = 'New Title'; // Our New Colomn Name
        $new[$key] = $title;
    }

    unset($new['title']); 
    return $new;
}

// Replace the title with your custom title
function replace_title_products($column_name, $post_ID) {
    if ($column_name == 'new-title') {
        $oldtitle = get_the_title();
        $newtitle = str_replace(array("<span class='sub-title'>", "</span>"), array("", ""),$oldtitle);
        $title = esc_attr($newtitle); 
        echo $title; 
    }
}

add_filter('manage_mycpt_columns', 'replace_title_column');
add_action('manage_mycpt_custom_column', 'replace_title_products', 10, 2);

Replace Columns

Here is an example that completely replaces the columns, rather than adding and removing specific ones

function set_book_columns($columns) {
    return array(
        'cb' => '<input type="checkbox" />',
        'title' => __('Title'),
        'comments' => '<span class="vers comment-grey-bubble" title="' . esc_attr__( 'Comments' ) . '"><span class="screen-reader-text">' . __( 'Comments' ) . '</span></span>',
        'date' => __('Date'),
        'publisher' => __('Publisher'),
        'book_author' =>__( 'Book Author')
    );
}
add_filter('manage_book_posts_columns' , 'set_book_columns');
