title: textboxes in HTML table: How to auto-size?
body: <p>I want to add a row at the bottom of my HTML table (or at the top, whatever) with a textbox in each column (to allow filtering of content of each column).</p>
  
  <p>FWIW, the table is based on the jQuery DataTables plug-in.</p>
  
  <p>The problem is that the textboxes widen the columns. I want each textbox to fill the width of its column without enlarging it. How can I do this?</p>
