title: React colspan not working
body: <p>Why colspan attribute doesn't have effect in React? I created simple component which renders the following:</p>
  
  <pre><code>&lt;table border="1"&gt;
    &lt;tr&gt;
      &lt;th colspan="2"&gt;people are...&lt;/th&gt;
    &lt;/tr&gt;
    &lt;tr&gt;
      &lt;td&gt;monkeys&lt;/td&gt;
      &lt;td&gt;donkeys&lt;/td&gt;
    &lt;/tr&gt;
  &lt;/table&gt;
  </code></pre>
  
  <p>and what I get is:</p>
  
  <p><a href="https://i.stack.imgur.com/6zZ5I.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/6zZ5I.jpg" alt="enter image description here"></a></p>
  
  <p>Am I missing something?</p>
  
  <p><strong>Edit: SOLVED</strong></p>
  
  <p>Here is the solution. React expects the attribute name as <em>colSpan</em>, not colspan. Figured this out after wasting ridiculous amount of time to discover this little evil fact.</p>
