Fix columns in horizontal scrolling

I am currently trying to fix my first column in a table when the user scroll in the X-axle.
I am using this structure:

<div class="table-wrapper">
<table id="consumption-data" class="data">
<thead class="header">
<tr>
<th>Month</th>
<th>Item 1</th>
</tr>
</thead>
<tbody class="results">
<tr>
<th>Jan</th>
<td>3163</td>
</tr>
<tr>
<th>Feb</th>
<td>3163.7</td>
</tr>
<tr>
<th>Mar</th>
<td>3163.7</td>
</tr>
<tr>
<th>Apr</th>
<td>3163.7</td>
</tr>
<tr>
<th>May</th>
<td>3163.7</td>
</tr>
<tr>
<th>Jun</th>
<td>3163.7</td>
</tr>

<tr>
<th>...</th>
<td>...</td>
</tr>
</tbody>
</table>
</div>


The number of items will be picked by the user, i.e. it could be 90 items in the table. This will require a scroll in the X-axle. The question i have got though is:

How do i fix the position of the th-tags inside the tbody (and the th:first-child in the theader)?

I have been looking at some other threads, however they do not really explain how i achieve the fixed columns which makes it hard for me to understand what the codes does and what i am supposed to do.

I have also checked on solutions where people split up the header-column in another table. This wont be possible for me because i will export the data to other systems later on.

My css:

.table-wrapper {
overflow-x:scroll;
overflow-y:visible;
}


This fixes the scroll, now comes the work with:

tbody th,
thead th:first-child {}


Anyone got any ideas?

SOLVED

http://jsfiddle.net/DJqPf/7/

.table-wrapper { 
    overflow-x:scroll;
    overflow-y:visible;
    width:250px;
    margin-left: 120px;
}
td, th {
    padding: 5px 20px;
    width: 100px;
}
th:first-child {
    position: fixed;
    left: 5px
}

UPDATE

$(function () {  
  $('.table-wrapper tr').each(function () {
    var tr = $(this),
        h = 0;
    tr.children().each(function () {
      var td = $(this),
          tdh = td.height();
      if (tdh > h) h = tdh;
    });
    tr.css({height: h + 'px'});
  });
});
body {
    position: relative;
}
.table-wrapper { 
    overflow-x:scroll;
    overflow-y:visible;
    width:200px;
    margin-left: 120px;
}


td, th {
    padding: 5px 20px;
    width: 100px;
}
tbody tr {
  
}
th:first-child {
    position: absolute;
    left: 5px
}
