title: Colspan all columns
body: <p>How can I specify a <code>td</code> tag should span all columns (when the exact amount of columns in the table will be variable/difficult to determine when the HTML is being rendered)? <a href="http://www.w3schools.com/tags/att_td_colspan.asp" rel="noreferrer">w3schools</a> mentions you can use <code>colspan="0"</code>, but it doesn't say exactly what browsers support that value (IE 6 is in our list to support). </p>
  
  <p>It appears that setting <code>colspan</code> to a value greater than the theoretical amount of columns you may have will work, but it will not work if you have <code>table-layout</code> set to <code>fixed</code>. Are there any disadvantages to using an automatic layout with a large number for <code>colspan</code>? Is there a more correct way of doing this?</p>
