title: HTML table with fixed headers?
body: <p>Is there a cross-browser CSS/JavaScript technique to display a long HTML table such that the column headers stay fixed on-screen and do not scroll with the table body. Think of the "freeze panes" effect in Microsoft Excel.</p>
  
  <p>I want to be able to scroll through the contents of the table, but to always be able to see the column headers at the top.</p>
