Answer 1

After spent three hours, I finally got it!

It's some Tableau behavior that hover doesn't work as well, can't say why.

Below it's my code explaining what I did to hover all lines.

import time

from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains

driver = webdriver.Chrome(executable_path='./chromedriver')
driver.maximize_window()
driver.implicitly_wait(0)
url = 'https://public.tableau.com/views/IRENA_Decentralised_RE_Data_Review_2019/ExploreData?:showVizHome=no'
driver.get(url)
time.sleep(2)

scroll = driver.find_element_by_xpath("//div[@class='tab-tvScrollY tvimages']"
                                      "[./div[@class='tvimagesContainer' and @style]]")
column = driver.find_elements_by_xpath("//canvas[@class='tabCanvas tab-widget']")[1]

action = ActionChains(driver)
for i in range(10000):
    driver.execute_script('arguments[0].scrollTop = (0,%s)' % str(i * 49), scroll)

    # Move cursor to hover element
    action.move_to_element_with_offset(column, 0, 0).perform()

    # Select HTML table
    table = driver.find_element_by_xpath("//div[@class='tab-tooltip tab-widget "
                                         "tab-tooltipBL tab-allowMouseEventPassthrough']")
    # Your selenium code to extract HTML content [...]

    # Move cursor to reset tableau hover function behavior
    action.move_to_element(scroll).perform()

Hope it helps!
