CSS: container to show PRE tag with scroll bars

I have some server-side code that outputs stuff in html <pre></pre> tags and I would like to be able to put them in a container with scroll bars. (Specifically, table cells - with equal widths). Obviously I want to preserve the <pre> tag whitespace formatting.

(see this jsfiddle):

HTML:

<table>
<tr>
    <th>Col 1</th>
    <th>Col 2</th>
</tr>
    <tr>
        <td><pre>
function thisIsATest(bla){
    Testing 123456789 Testing 123456789 Testing 123456789
}
        </pre></td>
        <td><pre>
function thisIsATest(bla){
    Testing 123456789 Testing 123456789 Testing 123456789
}
        </pre></td>
    </tr>
</table>

CSS:

table { 
    width: 100%; 
    border: 1px solid red;
}
td { 
    width: 50%;
    overflow: scroll; 
    border: 1px solid blue;
}

enter image description here

(I am testing it in Firefox). What am I doing wrong? Thanks

Update

The easiest way to fix this is to add: table-layout:fixed; (ironic) to the CSS for table

Fiddle

Original Answer:

Using pre tags within table elements is notoriously problematic, namely due to issues with relative width calculations which throw scrolling and actual width setting right out. As such, I'd avoid a table based setup, not least of which because you're also not displaying tabulated data (aaah semantics!).

I'd change your layout per the below:

Demo Fiddle

HTML

<div class='container'>
    <div class='col'> <pre>
function thisIsATest(bla){
    Testing 123456789 Testing 123456789 Testing 123456789
}
        </pre>

    </div>
    <div class='col'> <pre>
function thisIsATest(bla){
    Testing 123456789 Testing 123456789 Testing 123456789
}
        </pre>

    </div>
</div>

CSS

* {
    box-sizing:border-box;
}
html, body {
    margin:0;
    padding:0;
}
.container {
    border: 1px solid red;
    overflow:hidden;
}
.col {
    border: 1px solid blue;
    float:left;
    width:50%;
    overflow: auto;
}

Update

To fake a multi-line (row) table layout, use div element with dislpay set as appropriate:

Demo Fiddle

HTML

<div class='table'>
    <div class='row'>
        <div class='cell'> <pre>
function thisIsATest(bla){
    Testing 123456789 Testing 123456789 Testing 123456789
}
        </pre>

        </div>
        <div class='cell'> <pre>
function thisIsATest(bla){
    Testing 123456789 Testing 123456789 Testing 123456789
}
        </pre>

        </div>
    </div>
    <div class='row'>
        <div class='cell'> <pre>
function thisIsATest(bla){
    Testing 123456789 Testing 123456789 Testing 123456789
}
        </pre>

        </div>
        <div class='cell'> <pre>
function thisIsATest(bla){
    Testing 123456789 Testing 123456789 Testing 123456789
}
        </pre>

        </div>
    </div>
</div>

CSS

* {
    box-sizing:border-box;
}
html, body {
    margin:0;
    padding:0;
}
.table {
    border: 1px solid red;
    display:table;
    table-layout:fixed;
    width:100%;
}
.cell {
    border: 1px solid blue;
    overflow: auto;
    display:table-cell;
}
.row {
    display:table-row;
}
