title: Nightwatch.js loop through table
body: <p>I am using Nightwatch.js to write some System Tests. Now I want to loop through all elements of a table and check their values. How can I do this with Nightwatch.js? The table has a <code>&lt;tbody&gt;</code> element containing several rows <code>&lt;tr&gt;</code>. Every row has several columns <code>&lt;td&gt;</code>. I want to get the values of every first <code>&lt;td&gt;</code> element in every row.</p>
