title: How to have html table's height = height of parent div when div's height is not set
body: <p>I have an html table, inside of a div. The div's height is based on other elements in the div.</p>
  
  <p>How can I have the table's height be equal to its parent div's height?</p>
  
  <p>(table height: 100% won't work because the div's height is not set)</p>
  
  <p><strong>Update:</strong> I need to support IE6,7,8 so the css recommendations should be understood by  these browsers.</p>
