Selenium Python missing data

I managed a solution after the comment by @PApostol, the problem is that the data is not visible in the initial layout, so I expanded the screen and made it scroll to the right, it misses the first data by this approach, so its necessary to concatenate the data before and after scrolling, heres the code:

driver = webdriver.Firefox()
url = 'https://www.macrotrends.net/stocks/charts/AAPL/apple/financial-statements'
hdr = {"User-Agent": "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.75 Safari/537.36",
  "X-Requested-With": "XMLHttpRequest"}
driver.get(url)
driver.set_window_size(2000, 2000)
a = driver.find_element(By.CSS_SELECTOR, "#contenttablejqxgrid").text
arrow = driver.find_element(By.CSS_SELECTOR, ".jqx-icon-arrow-right")
webdriver.ActionChains(driver).click_and_hold(arrow).perform()
time.sleep(4)
b = driver.find_element(By.CSS_SELECTOR, "#contenttablejqxgrid").text
print(a,b)

Thanks!
