title: Why use the th element instead of td element?
body: <p>I'm reading up on the differences between the HTML <code>th</code> and <code>th</code> elements used in <code>&lt;table&gt;</code></p>
  
  <p>According to <a href="http://webdesign.about.com/od/tables/f/blfaqthvstd.htm" rel="nofollow noreferrer">http://webdesign.about.com/od/tables/f/blfaqthvstd.htm</a> , the <code>th</code> element <code>defines the current cell as a table header.</code> </p>
  
  <p>It then goes on to say that some browsers will render the <code>th</code> element differently (defined by the browser) but the article then advises not to style the TH ourselves (via CSS I assume).</p>
  
  <p>I'm completely confused by this; It is suggesting that to use <code>th</code> element gives us no design control and has no value/importance...</p>
  
  <p>I know some elements are older and some become obsolete, but I find no mention that the <code>th</code> element is depreciated nor can I see any value in it. </p>
  
  <p>Would some one let me know if I've miss-understood please. Does Google read TH differently (again, my research shows nothing), does the <code>th</code> element help the browser to render the table, or is it just an option to use if we want to?</p>
