Scrapy Splash - I am not able to get the value

Question

I am trying to scrape this page: https://simple.ripley.com.pe/laptop-lenovo-ideapad-5-amd-ryzen-7-16gb-ram-256gb-ssd-14-2004286061746p?s=o

All ok, but I am not able to get the values in this xpath: //*[@id="panel-Especificaciones"]/div/div/table/tbody/tr[19]/td[2]

I think it loads dynamically. It's a table with many rows inside. I would like to get those values.

Image: page section i can't scrape

This is my spider code:

import scrapy
from scrapy_splash import SplashRequest
from numpy import nan

LUA_SCRIPT = """
function main(splash)
    splash.private_mode_enabled = false
    splash:go(splash.args.url)
    splash:wait(2)
    html = splash:html()
    splash.private_mode_enabled = true
    return html
end
"""

class RipleySpider(scrapy.Spider):
    name = "ripley"
    
    def start_requests(self):
        url = 'https://simple.ripley.com.pe/tecnologia/computacion/laptops?facet%5B%5D=Procesador%3AIntel+Core+i7'
        yield SplashRequest(url=url, callback=self.parse)

    def parse(self, response):
        for link in response.xpath("//div[@class='catalog-container']/div/a/@href"):
            yield response.follow(link.get(), callback=self.parse_products)

        # for href in response.xpath("//ul[@class='pagination']/li[last()]/a/@href").getall():
        #     yield SplashRequest(response.urljoin(href), callback=self.parse)

    def parse_products(self, response):
        titulo =  response.css("h1::text").get()
        link = response.request.url
        sku = response.css(".sku-value::text").get()

        precio = response.css(".product-price::text").getall()
        if len(precio)==1: 
            precio_normal = nan
            precio_internet = precio[0]
            precio_tarjeta_ripley = nan
        elif len(precio)==2:
            precio_normal = precio[0]
            precio_internet = precio[1]
            precio_tarjeta_ripley = nan
        elif len(precio)==4:
            precio_normal = precio[0]
            precio_internet = precio[1]
            precio_tarjeta_ripley = precio[-1]

        try:
            # descripcion = response.css(".product-short-description::text").get()
            descripcion = response.xpath('//*[@id="panel-Especificaciones"]/div/div/table/tbody/tr[1]/td[2]/text()').get()
        except:
            descripcion = 'sin valor'

        yield {
            'Título': titulo,
            'Link': link,
            'SKU': sku,
            'Precio Normal': precio_normal,
            'Precio Internet': precio_internet,
            'Precio Tarjeta Ripley': precio_tarjeta_ripley,
            'Descripción': descripcion,
        }

Please, what solutions does scrapy offer? Thanks in advance for your help.

P.D.: I'm using Docker with Splash in localhost:8050. settings.py according to documentation.
