How to solve find_element_by_class_name() throwing "Unable to find element with class name '...'"?

The webpage (see driver.get() below) seems to have one table with class name as table. I can't seem to locate it using the code below.

I was under the impression that I could locate these type of Javascript elements using Selenium. 

import time

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

driver.quit()
driver = webdriver.PhantomJS()

driver.get('http://investsnips.com/list-of-publicly-traded-micro-cap-diversified-biotechnology-and-pharmaceutical-companies/')


content = driver.find_element_by_css_selector('table.table')
x = driver.find_element_by_class_name("table")

I'm getting this error (content nor x work)

NoSuchElementException: Message: {"errorMessage":"Unable to find element with class name 'table'","request":{"headers":{"Accept":"application/json","Accept-Encoding":"identity","Connection":"close","Content-Length":"94","Content-Type":"application/json;charset=UTF-8","Host":"127.0.0.1:49464","User-Agent":"Python http auth"},"httpVersion":"1.1","method":"POST","post":"{\"using\": \"class name\", \"value\": \"table\", \"sessionId\": \"a988f310-65da-11e7-a655-01f6986e9e41\"}","url":"/element","urlParsed":{"anchor":"","query":"","file":"element","directory":"/","path":"/element","relative":"/element","port":"","host":"","password":"","user":"","userInfo":"","authority":"","protocol":"","source":"/element","queryKey":{},"chunks":["element"]},"urlOriginal":"/session/a988f310-65da-11e7-a655-01f6986e9e41/element"}}

The table in in iframe. You have to switch iframe before finding the table. See code below.

driver = webdriver.PhantomJS()

driver.get('http://investsnips.com/list-of-publicly-traded-micro-cap-diversified-biotechnology-and-pharmaceutical-companies/')

#Find the iframe tradingview_xxxxx and then switch into the iframe
iframeElement = driver.find_element_by_css_selector('iframe[id*="tradingview_"]')
driver.switch_to_frame(iframeElement)
#Wait for the table
waitForPresence = WebDriverWait(driver, 10)
waitForPresence.until(EC.presence_of_element_located((By.CSS_SELECTOR,'table.table'))
theTable = driver.find_element_by_css_selector('table.table')
