How to add checkbox column in WooCommerce product listing in WordPress admin panel to update meta value with ajax

Question

I have to add an extra column with checkbox to WordPress/WooCommerce product listing in the admin panel.

Its purpose is to quickly update extra meta parameter of the product without entering quick edit.

I added a checkbox column, but I have a problem with placing the column before the featured star column as on the attached image. How to update meta with ajax in such case?

Current code:

add_action( 'manage_product_posts_custom_column', 'print_extra_columns', 15, 3 );
add_filter( 'manage_product_posts_columns', 'add_extra_columns', 15 );



function print_extra_columns( $value, $column_name )
{ 
   if(  $value  == "extra" ) {
        $checkbox ='<input type="checkbox" name="extra" />';
        echo  $checkbox;
}


}

function add_extra_columns( $defaults )
{
    $defaults['extra'] = 'Extra';
    return $defaults;
}

Actually this task can be implemented in 4 steps:

1. Add a column with manage_edit-product_columns (You did it!)
2. Populate column with a checkbox using manage_posts_custom_column (You did it!)
3. jQuery/JavaScript code to send async request to wp_ajax_ action hook (To do!)
4. Process the AJAX request and save the value to post meta (To do!)
