title: Create a table with sub-headings and side-headings
body: <p>I am trying to create a table with sub-headings and side-headings which looks like the picture below:</p>
  
  <p><img src="https://i.stack.imgur.com/3hFTl.png" alt="enter image description here"></p>
  
  <p>This is what I have so far:</p>
  
  <pre><code>&lt;table&gt;
      &lt;thead&gt;
      &lt;tr&gt;
          &lt;th&gt;Object&lt;/th&gt;
          &lt;th&gt;Openings&lt;/th&gt;
          &lt;th&gt;Internal Dimensions&lt;/th&gt;
              &lt;th&gt;Weight&lt;/th&gt;
              &lt;th&gt;Volume&lt;/th&gt;
      &lt;/tr&gt;
      &lt;/thead&gt;
      &lt;tbody&gt;
      &lt;tr&gt;
          &lt;td&gt;Box&lt;/td&gt;
          &lt;td&gt;300x500&lt;/td&gt;
          &lt;td&gt;300cm x 400cm x 600cm&lt;/td&gt;
          &lt;td&gt;Min: 100g, Max: 200g, NA&lt;/td&gt;
          &lt;td&gt;300&lt;/td&gt;
      &lt;/tr&gt;
      &lt;/tbody&gt;
  &lt;/table&gt;
  </code></pre>
  
  <p>Is it possible to have a table that looks similarly to the picture above.</p>
