Site performance down with Ninja Tables

This issue https://www.ads-software.com/support/topic/site-performance-down-with-ninja-tables/ is not resolved.

What can you do with fonts? i setup “theme fonts” into table configuration and so i don’t need this fonts. This fonts degrade my site performance. I can’t remove that font because the implementation is one of the worst code i ever seen.

Call this function:

function ninjaTablePreloadFont()
{
    add_action('wp_head', function () {
        $preloadFontUrl = NINJA_TABLES_DIR_URL . "assets/fonts/ninja-tables.woff2?" . NINJA_TABLES_PRELOAD_FONT_VERSION;
        ?>
        <link rel="preload" as="font" href="<?php echo esc_url($preloadFontUrl) ?>" type="font/woff2"
              crossorigin="anonymous">
        <?php
    }, 99);
}

Into this method :

 /**
     * Enqueue main public css.
     */
    public static function enqueuePublicCss()
    {
        $styleSrc = NINJA_TABLES_DIR_URL . "assets/css/ninjatables-public.css";

        if (is_rtl()) {
            $styleSrc = NINJA_TABLES_DIR_URL . "assets/css/ninjatables-public-rtl.css";
        }

        wp_enqueue_style(
            'footable_styles',
            $styleSrc,
            array(),
            self::$version,
            'all'
        );

        ninjaTablePreloadFont();
    }
