title: ValueError: Length of values (221) does not match length of index (189)
body: <p>I am trying to add my lists to columns in my dataframes but some of the lists have more data in them compared to others. I am getting the following error:</p>
  <pre><code> ValueError: Length of values (221) does not match length of index (189)
  </code></pre>
  <p>The data in each column does match with eachother so it all matches up in a row. Is there a way to get this to work with the data? Maybe add NaN values or null?</p>
  <p>Sample List 1:</p>
  <pre><code>['Defense Evasion', 'Privilege Escalation', 'Defense Evasion', 'Privilege Escalation']
  </code></pre>
  <p>Sample List 2:</p>
  <pre><code>['Windows Management Instrumentation', 'XSL Script Processing', 'Domain Policy Modification', 'Forge Web Credentials']
  </code></pre>
  <p>Sample List 3:</p>
  <pre><code>['Blue MockingBird', 'FIN6']
  </code></pre>
  <p>Expected data-frame:</p>
  <pre><code>Tactic                   Name                               Actor
  Defense Evasion       Windows Management Instrumentation      Blue Mocking Bird
  Privilege Escalation   XSL Script Processing                  
  Defense Evasion        Domain Policy Modification             Fin 6
  Privilege Escalation    Forge Web Credentials
  </code></pre>
