    <p>I think the general approach is:</p> <ol> <li>Create a hash for each table where the key is the employee</li> <li>Merge the results from both tables together</li> <li>Convert to JSON</li> </ol> <p><strong>Create a hash for each table where the key is the employee</strong></p> <p>This part you can do in Watir or Nokogiri. It only makes sense to use Nokogiri if Watir is giving poor performance due large tables.</p> <p>Watir:</p> <pre><code>#I assume you would have a better way to identify the tables than by index hours_table = browser.table(:index, 0) wage_table = browser.table(:index, 1) #Turn the tables into a hash employee_hours = {} hours_table.trs.drop(1).each do |tr| tds = tr.tds employee_hours[ tds[0].text ] = {"Reg Hours" =&gt; tds[1].text, "OT Hours" =&gt; tds[2].text} end #=&gt; {"Employee 1"=&gt;{"Reg Hours"=&gt;"10", "OT Hours"=&gt;"20"}, "Employee 2"=&gt;{"Reg Hours"=&gt;"5", "OT Hours"=&gt;"10"}} employee_wage = {} wage_table.trs.drop(1).each do |tr| tds = tr.tds employee_wage[ tds[0].text ] = {"Revenue" =&gt; tds[1].text} end #=&gt; {"Employee 2"=&gt;{"Revenue"=&gt;"$10"}, "Employee 1"=&gt;{"Revenue"=&gt;"$50"}} </code></pre> <p>Nokogiri:</p> <pre><code>page = Nokogiri::HTML.parse(browser.html) hours_table = page.search('table')[0] wage_table = page.search('table')[1] employee_hours = {} hours_table.search('tr').drop(1).each do |tr| tds = tr.search('td') employee_hours[ tds[0].text ] = {"Reg Hours" =&gt; tds[1].text, "OT Hours" =&gt; tds[2].text} end #=&gt; {"Employee 1"=&gt;{"Reg Hours"=&gt;"10", "OT Hours"=&gt;"20"}, "Employee 2"=&gt;{"Reg Hours"=&gt;"5", "OT Hours"=&gt;"10"}} employee_wage = {} wage_table.search('tr').drop(1).each do |tr| tds = tr.search('td') employee_wage[ tds[0].text ] = {"Revenue" =&gt; tds[1].text} end #=&gt; {"Employee 2"=&gt;{"Revenue"=&gt;"$10"}, "Employee 1"=&gt;{"Revenue"=&gt;"$50"}} </code></pre> <p><strong>Merge the results from both tables together</strong></p> <p>You want to merge the two hashes together so that for a specific employee, the hash will include their hours as well as their revenue.</p> <pre><code>employee = employee_hours.merge(employee_wage){ |key, old, new| new.merge(old) } #=&gt; {"Employee 1"=&gt;{"Revenue"=&gt;"$50", "Reg Hours"=&gt;"10", "OT Hours"=&gt;"20"}, "Employee 2"=&gt;{"Revenue"=&gt;"$10", "Reg Hours"=&gt;"5", "OT Hours"=&gt;"10"}} </code></pre> <p><strong>Convert to JSON</strong></p> <p>Based on this <a href="https://stackoverflow.com/questions/3183786/how-to-convert-a-ruby-hash-object-to-json">previous question</a>, you can then convert the hash to json.</p> <pre><code>require 'json' employee.to_json </code></pre>

    1. COThanks for your reply. I made the following change: hours_table = browser.tr(:xpath, '//*[@id="tblReportItems"]/tbody/tr[1]') because it looks like the table ids have now disappeared. Getting an "undefined method 'hashes' error" now, though, from water-webdriver.

    2. CO`hashes` is defined for tables, not trs. In other words, you need to ensure that `hours_table` is still a table. Based on your suggested change, you should be able to do `hours_table = browser.table(:id => 'tblReportItems')`.

    3. COI see...but that table ID is for an all-encompassing table. The tables I need are within that table (with no IDs). Trying your nokogiri example, I get an undefined method error for 'text'.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
