The implementation of webdriverIo is slightly different from selenium.

In webdriverIO `$('table').$$('td')` will check for direct child 'td under 'table', and as td is not a direct child it won't return anything.

instead, try:

    $('table').$$(' td') (See if this works)

or

    $$('table td')


Space in 'CSS' is similar to // in xpath


Better raise issue with webdriver io
