I am trying to design an HTML table where the header will stay at the top of the page when AND ONLY when the user scrolls it out of view. For example, the table may be 500

    There are many really good solution here already. But one of the simplest CSS only solutions that I use in these situations is as follows:

    table {
      /* Not required only for visualizing */
      border-collapse: collapse;
      width: 100%;
    }
    
    table thead tr th {
      /* Important */
      background-color: red;
      position: sticky;
      z-index: 100;
      top: 0;
    }
    
    td {
      /* Not required only for visualizing */
      padding: 1em;
    }
    <table>
      <thead>
        <tr>
          <th>Col1</th>
          <th>Col2</th>
          <th>Col3</th>
        </tr>
      </thead>
      <tbody>
         <tr>
           <td>info</td>
           <td>info</td>
           <td>info</td>
         </tr>
         <tr>
           <td>info</td>
           <td>info</td>
           <td>info</td>
         </tr>
         <tr>
           <td>info</td>
           <td>info</td>
           <td>info</td>
         </tr>
         <tr>
           <td>info</td>
           <td>info</td>
           <td>info</td>
         </tr>
         <tr>
           <td>info</td>
           <td>info</td>
           <td>info</td>
         </tr>
         <tr>
           <td>info</td>
           <td>info</td>
           <td>info</td>
         </tr>
         <tr>
           <td>info</td>
           <td>info</td>
           <td>info</td>
         </tr>
         <tr>
           <td>info</td>
           <td>info</td>
           <td>info</td>
         </tr>
         <tr>
           <td>info</td>
           <td>info</td>
           <td>info</td>
         </tr>
         <tr>
           <td>info</td>
           <td>info</td>
           <td>info</td>
         </tr>
         <tr>
           <td>info</td>
           <td>info</td>
           <td>info</td>
         </tr>
         <tr>
           <td>info</td>
           <td>info</td>
           <td>info</td>
         </tr>
      </tbody>
    </table>

    Because there is no requirement for JavaScript it simplifies the situation significantly. You essentially need to focus on the second CSS rule, which contains the conditions for ensuring that the head of the table remains of the top no matter the scroll space.

    To elaborate on each of the rules in detail. position is meant to indicate to the browser that the head object, its row, and its cells all need to stick to the top. This necessarily needs to be accompanied by top, which specifies to the browser that the head will stick to the top of the page or viewport. Additionally, you can add z-index to ensure that the content of the head always remains on the top.

    The background colour is merely to illustrate the point. You do not need to use any additional JavaScript to get this effect. This is supported in most major browsers after 2016.

    A bit late to the party, but here is an implementation that works with multiple tables on the same page and "jank" free (using requestAnimationFrame). Also there's no need to provide any width on the columns. Horizontal scrolling works as well.

    The headers are defined in a div so you are free to add any markup there (like buttons), if required. This is all the HTML that is needed:

    <div class="tbl-resp">
      <table id="tbl1" class="tbl-resp__tbl">
         <thead>
          <tr>
            <th>col 1</th>
            <th>col 2</th>
            <th>col 3</th>
          </tr>
        </thead> 
      </table>
    </div>

    Fix your issue with this

    tbody {
      display: table-caption;
      height: 200px;
      caption-side: bottom;
      overflow: auto;
    }

    I too experienced the same issues with the border formatting not being shown using entrophy's code but a few little fixes and now the table is expandable and displays all css styling rules you may add.

    to css add:

    #maintable{width: 100%}    
    

    then here is the new javascript:

        function moveScroll(){
        var scroll = $(window).scrollTop();
        var anchor_top = $("#maintable").offset().top;
        var anchor_bottom = $("#bottom_anchor").offset().top;
        if (scroll > anchor_top && scroll < anchor_bottom) {
            clone_table = $("#clone");
            if(clone_table.length === 0) {          
                clone_table = $("#maintable").clone();
                clone_table.attr({id: "clone"})
                .css({
                    position: "fixed",
                    "pointer-events": "none",
                     top:0
                })
                .width($("#maintable").width());
    
                $("#table-container").append(clone_table);
                // dont hide the whole table or you lose border style & 
                // actively match the inline width to the #maintable width if the 
                // container holding the table (window, iframe, div) changes width          
                $("#clone").width($("#maintable").width());
                // only the clone thead remains visible
                $("#clone thead").css({
                    visibility:"visible"
                });
                // clone tbody is hidden
                $("#clone tbody").css({
                    visibility:"hidden"
                });
                // add support for a tfoot element
                // and hide its cloned version too
                var footEl = $("#clone tfoot");
                if(footEl.length){
                    footEl.css({
                        visibility:"hidden"
                    });
                }
            }
        } 
        else {
            $("#clone").remove();
        }
    }
    $(window).scroll(moveScroll);

    This is by far the best solution I've found for having a fixed table header.

    UPDATE 5/11: Fixed horizontal scrolling bug as pointed out by Kerry Johnson

    Codepen: https://codepen.io/josephting/pen/demELL

    ;(function($) {
       $.fn.fixMe = function() {
          return this.each(function() {
             var $this = $(this),
                $t_fixed;
             function init() {
                $this.wrap('<div class="container" />');
                $t_fixed = $this.clone();
                $t_fixed.find("tbody").remove().end().addClass("fixed").insertBefore($this);
                resizeFixed();
             }
             function resizeFixed() {
               $t_fixed.width($this.outerWidth());
                $t_fixed.find("th").each(function(index) {
                   $(this).css("width",$this.find("th").eq(index).outerWidth()+"px");
                });
             }
             function scrollFixed() {
                var offsetY = $(this).scrollTop(),
                offsetX = $(this).scrollLeft(),
                tableOffsetTop = $this.offset().top,
                tableOffsetBottom = tableOffsetTop + $this.height() - $this.find("thead").height(),
                tableOffsetLeft = $this.offset().left;
                if(offsetY < tableOffsetTop || offsetY > tableOffsetBottom)
                   $t_fixed.hide();
                else if(offsetY >= tableOffsetTop && offsetY <= tableOffsetBottom && $t_fixed.is(":hidden"))
                   $t_fixed.show();
                $t_fixed.css("left", tableOffsetLeft - offsetX + "px");
             }
             $(window).resize(resizeFixed);
             $(window).scroll(scrollFixed);
             init();
