title: IE/FF-compatible HTML table with fixed header and footer, scrollable vertically and horizontally
body: <p>I need an HTML super-table of a sorts. It's fine if it's based on jQuery or some other JavaScript library. In fact I don't really care what the drawbacks are provided that the following requirements are met.</p>
  
  <p>Must support:</p>
  
  <ol>
  <li>At least IE8 and the most recent version of Firefox</li>
  <li>Variable-width columns (no pre-defined widths)</li>
  <li>A fixed header <strong>and</strong> a fixed footer</li>
  <li>Both horizontal <strong>and</strong> vertical scrolling</li>
  </ol>
  
  <p>I've found a whole bunch of them that satisfy some or many of these requirements, but not a single one that satisfies all of them.</p>
  
  <p>Does such a thing exist? Is it possible at all?</p>
