horizontal scrollbar on top and bottom of table

I've a very large table on my page. So I decided to put a horizontal scrollbar on the bottom of the table. But I would like this scrollbar to be also on top on the table.

What I have in the template is this:

<div style="overflow:auto; width:100%; height:130%">
<table id="data" style="width:100%">...</table>
</div>

Is this possible to do in HTML and CSS only?

Solution 1:

To simulate a second horizontal scrollbar on top of an element, put a "dummy" div above the element that has horizontal scrolling, just high enough for a scrollbar. Then attach handlers of the "scroll" event for the dummy element and the real element, to get the other element in synch when either scrollbar is moved. The dummy element will look like a second horizontal scrollbar above the real element.

For a live example, see this fiddle

Here's the code:

HTML:

<div class="wrapper1">
  <div class="div1"></div>
</div>
<div class="wrapper2">
  <div class="div2">
    <!-- Content Here -->
  </div>
</div>

CSS:

.wrapper1, .wrapper2 {
  width: 300px;
  overflow-x: scroll;
  overflow-y:hidden;
}

.wrapper1 {height: 20px; }
.wrapper2 {height: 200px; }

.div1 {
  width:1000px;
  height: 20px;
}

.div2 {
  width:1000px;
  height: 200px;
  background-color: #88FF88;
  overflow: auto;
}

JS:

$(function(){
  $(".wrapper1").scroll(function(){
    $(".wrapper2").scrollLeft($(".wrapper1").scrollLeft());
  });
  $(".wrapper2").scroll(function(){
    $(".wrapper1").scrollLeft($(".wrapper2").scrollLeft());
  });
});

Solution 2:

Try using the jquery.doubleScroll plugin :

jQuery :

$(document).ready(function(){
  $('#double-scroll').doubleScroll();
});

CSS :

#double-scroll{
  width: 400px;
}

HTML :

<div id="double-scroll">
  <table id="very-wide-element">
    <tbody>
      <tr>
        <td></td>
      </tr>
    </tbody>
  </table>
</div>

Solution 3:

Without JQuery (2017)

Because you might not need JQuery, here is a working Vanilla JS version based on @StanleyH answer:

var wrapper1 = document.getElementById('wrapper1');
var wrapper2 = document.getElementById('wrapper2');
wrapper1.onscroll = function() {
  wrapper2.scrollLeft = wrapper1.scrollLeft;
};
wrapper2.onscroll = function() {
  wrapper1.scrollLeft = wrapper2.scrollLeft;
};

#wrapper1, #wrapper2{width: 300px; border: none 0px RED;
overflow-x: scroll; overflow-y:hidden;}
#wrapper1{height: 20px; }
#wrapper2{height: 100px; }
#div1 {width:1000px; height: 20px; }
#div2 {width:1000px; height: 100px; background-color: #88FF88;
overflow: auto;}

<div id="wrapper1">
    <div id="div1">
    </div>
</div>
<div id="wrapper2">
    <div id="div2">
    aaaa bbbb cccc dddd aaaa bbbb cccc 
    dddd aaaa bbbb cccc dddd aaaa bbbb 
    cccc dddd aaaa bbbb cccc dddd aaaa 
    bbbb cccc dddd aaaa bbbb cccc dddd
    </div>
</div>
