How to add data to product item line on order preview

[LeFlow]

Hi.

With a plugin, on the order preview (by clicking on the little eye ^^), I would like to add "the line number" or "order item" for each of the products in the invoice.

I'm editing this post again because I had a perhaps better idea which is to add a new column to the table that displays product details.

My following code displays the new connection correctly, the HTML structure of the table is correct, however, for each product line, the column data is not displayed. (I used random text to avoid possible data recovery problems)

function custom_wc_order_preview_table_content($item, $args) {
    if ($item->is_type('line_item')) {
        $random_text = substr(str_shuffle("abcdefghijklmnopqrstuvwxyz"), 0, 5);
        if ('new' === $args['column_id']) {
            echo '<td class="wc-order-preview-table__column--new">'; 
            echo $random_text;
            echo '</td>';
        }
    }
}
add_action('woocommerce_admin_order_preview_line_item_column', 'custom_wc_order_preview_table_content', 10, 2);

function custom_wc_order_preview_table_header($columns) {
    $new_columns = array('new' => __('Nouvelle colonne', 'woocommerce'));
    $columns = array_slice($columns, 0, 1, true) + $new_columns + array_slice($columns, 1, count($columns) - 1, true);
    return $columns;
}
add_filter('woocommerce_admin_order_preview_line_item_columns', 'custom_wc_order_preview_table_header');

function custom_wc_order_preview_table_css() {
    echo '<style>.wc-order-preview-table__column--new { width: 20%; }</style>';
}
add_action('admin_head', 'custom_wc_order_preview_table_css');

I don't know if it's clear but thank you in advance for your help.

Thank you to those who searched even without finding or giving results but I found a solution that suits me (to see if it will suit my boss when I return from this vacation ^^):

// Add new column
function filter_woocommerce_admin_order_preview_line_item_columns( $columns, $order ) { 
    // Add a new column
    $new_column['info'] = __( 'n°', 'woocommerce' );

    // Return new column as first
    return $new_column + $columns;
}
add_filter( 'woocommerce_admin_order_preview_line_item_columns', 'filter_woocommerce_admin_order_preview_line_item_columns', 10, 2 );

function filter_woocommerce_admin_order_preview_line_item_column_info( $html, $item, $item_id, $order ) {
    // Get line item ID
    $line_item_id = $item_id;

    // Display line item ID as info
    $html = '#' . $line_item_id;

    return $html;

}
add_filter( 'woocommerce_admin_order_preview_line_item_column_info', 'filter_woocommerce_admin_order_preview_line_item_column_info', 10, 4 );

// CSS style
function add_order_notes_column_style() {
    $css = '.wc-order-preview .wc-order-preview-table td, .wc-order-preview .wc-order-preview-table th { text-align: left; } .wc-order-preview-table__column--info { padding-right: 0!important; width: 40px; }';
    wp_add_inline_style( 'woocommerce_admin_styles', $css );
}
add_action( 'admin_print_styles', 'add_order_notes_column_style' );

Thank you all
